    You have absolutely no idea what it does and yet you want one , geeze whats is this world coming to ?

    Yes you can get one for your gun and they come in all kinds of designs and at different price ranges , the simplest and cheapest to get would be the ones that replace your barrel bushing assuming you know what that is .

    The function of a Comp is to reduce recoil by directing the gas upward when a round is fired .

    I've never personally played with one so I have no idea how well they work the cheapest one you could perhaps try would be what CDNNSports Inc. sells for $19.99 .

    I am inclined to agree with my colleage above. Why do you want something, to add to your weapon, that you don't know what it is, or really what it does?

    First off, your 1991 should be all steel construction, so it should have good weight to it. Unless you are so small that you owe muscle mass, you probably are not going to be "need" a compensator unless you are doing some radical stuff like really fast double taps or multiple target timed drills. If you are, well, then, I don't think the 1991 should have been your first choice.

    The function of the compensator is to vent gas up, over the muzzle, to reduce muzzle flip and get you back on target faster. It will also moderately tame recoil, but nothing to write home about.

    I don't personally know of anyone who uses them. I don't even know any competing IPSC shooters, so I can't say they would or would not.

    My suggestion would be to put 500 rounds through the gun and see what YOU think about the weapon and it's recoil.

    A 45ACP isn't a high pressure round which would benefit much from a compensator. The best way to control the recoil in a 1911, is to intall a flat bottom firingpin stop from EGW (Evolutionary Gun Woks) a 23lb mainspring,and a 14lb recoil spring. With this setup,my 1911's operate smoother than any 9mm I have ever shot.

    It's your piece, do what you want with it. I've seen bushing comps before. Try Wilson Combat maybe? If not, Google "bushing comp 1911" with the quotes.

    I got one of those barrel bushing compensators last year for my 1911. I bought it just as an experimental thing to see if it would really work. Don't waste your money, it's really tight when it's new. I had to put some oil on it and work the slide and then fire it some to get it to loosen up. When I first put it on there, it would hold the slide back, that's how tight it was. I didn't notice a whole lot of difference with or without it. So I don't think it was really worth the $12, plus shipping and handeling required to get it to Indiana from Abilene Texas. I got it from CDNN Sports. I've fired the pistol with comp attached in the back yard but I've never carried it in public with it.

    The picture of the Gun Here on my avatar is a compesator and you cant buy it for 19.99 try $170 it is Titanium and its purpose as they all have told you is to count down recoil on high presure loads in competition mostly, there are some guns that come from the factory with comps, if you really want one and I am not sure why, a 45 is not a competive gun in the Open Class of guns with Comps only 9 mm and 38 Super, I have to guns with Compensators this one you are looking at 9mm 1911 by Springfield and a 2011 USPSA gun by STI, to do it right you will have to buy a threaded barrel for a Comp $225 and a good comp $170 now your at $395 now you need a Good Pistol smith to fit the Barrel and Comp and cut the slide to make it fit to the Comp about $600 So now your at $995 do you still want a Compensator???

    I will save you time and effort if you want a real compensated gun, I will sell you this gun $1900


    Springfield Armory
    9mm
    Starting from the rear
    Doug Koenig hammer
    Triglide (SVI) Titanium Sear Spring
    EGW Sear
    EGW Diconnect
    WILSON Highride Ambi Safety
    Slide work Cut and Lighten
    Shueman Match Grade Bushing Less (Bull) Barrel Threaded
    Bidell 7 port Titanium Compensator Cut down to 3 Ports ( there is a Reason for that)
    2 1/2 pound Trigger pull
    ISMI 7 pound recoil spring
    Will shoot 1 inch groups at 25 yards

    This gun will shoot any high pressure loads(8.2 gr. HS6 125 gr FMJ) and any low low presure loads (3.7 WST 147 Lead FP), one reason for gutting comp.

    With no recoil either way, no muzzle flip, in other words the gun will not move in your hand when fired low or high.

    If you have a 9mm try a 147 gr bullet at 3.7 gr of WST or 231 see if your slide will even make it all the way back.

    This same gun and what it will do both low and high Springfield was advertiseing at over $3000, but not built by Springfield

    What part are you talking about being reality, the over $300 to thread the barrel, or that comp on a 45 is only good for heavy loads, I can understand that, I had a comp 45 from the factory and light loads shot but it did not really operate the comp, fact, the gun shown will shoot below any book specifications on load data, below minor power factor and will feel as if you were shooting a 22, when I bought the Barrel from Will Shueman I told him what I wanted to do for a Steel Plate Gun just for the fun of it he then instructed us as what was needed, one it had to be set up perfectly and that 98% of the people building 1911 are not, it is way to time consuming to TIME a 1911, and to go according to Wills Specifications, and the instructions that come with his barrels, we tested for three months under his guidance until after every burr that could cause friction was removed, then finally we got it.
    I drove my buddy nuts who was doing the machine work,I did allot of hand sanding, Will Shueman talked us through it all the way, it all started when I saw Spingfields Addvertisement on their open gun that would shoot major and minor for $3200 I have about $2200 and countless hours and about 2000 rounds through it and never a hickup unless I screw up loading like a high primer.




    I think I have been to your site before your guns or Fabulous looking.

    For those of you who may not be familiar with who Will Shueman is, he is considered the GURU of the 1911s by most, his barrels are in every SVI gun and he even set up machines at SVI factory so they could build his barrel on site and desighned their Slide if you want to know anything about a 1911 call Will he is like talking to a Rocket Scientist great guy.

    The discussion was about installing a compensator and the prices are all over the place. The link showing the cost of $335 was for the total cost of the comp, installation and all the parts to install that particular comp.

    As far as that comp not being for light loads, it is designed for full power ammo. The amount of pressure from the ports of that compensator will push down on the barrel, slide and frame. The pressure causes friction and the slide will not cycle properly.

    To install a comp on a gun that is to be used with light loads will require different things to be changed. A smaller less efficient comp that doesn't push down as much, a lightened slide, lighter comp/barrel, lighter recoils spring, timing, etc. will all need to be considered.

    Sure, absolutely it takes a bunch to make one shoot light I learned that.

    What do you think of this, Will told me anything over 3 ports does nothing even for major pf loads, my USPSA gun is a 3 port Steel comp but I see allot of guys useing 7 port What do you think?

    Thanks for your info

    I guess that I can't agree with that, I install comps with more than 3 ports all the time and I can see a difference. It all depends on what the customer is looking for.

    For a racegun, 3-4 vertical ports seem to work the best for major loads. The size and number of ports will depend on the caliber, powder, and weight of dynamic parts. The side ports are bleeders that reduce the recoil but don't do anything for the flip and they add wight. So it depends on what they are looking for in the comp.

    I have installed comps with 4 big vertical ports and light slides. For me, the comp actually dips down rather than flips up. That is not good for me, but some shooter that have a weaker grip like them because the gun shoots flat for them.

    So there is no best set up for everyone. That is where custom built guns come into play. They are built to the customers needs.

    You know I have a 4 port vertical sitting in my parts box I did not like it but I really was not sure why, so I put a Stainless EGW 3 port on my USPSA gun and I like it just fine, we just did more slide work it was to heavy in front, we have horizontal groves and we just ported the top front I will shoot Sunday, and see if the weight feels better if not I may go to a bidell Titanium and cut it down to a 3 from a 7 like we did the steel gun, but I should really try it with 7, I guess you can see how un decided I am on my USPSA gun I bought this used it has about 10k rounds and I am getting to my liking, like you said its whatever a guy feels good with.

    I am useing 7.2 of 3 n 37 on my chrony it was low was 1336 fps avg was 1346 high was 1386, now my buddy who is a Master Class shooter just got a gun built by Millinium he said my chrony is off, he loading 8.2 of 3 n 37 so we have a big dispute one of us is off, were going to take both chronies and ck in a few wks he is shooting Tenn Sectional I guess this wk end, do you think 2 guns could be that different I think it is possible, but a grain of powder is a bunch, I am going to bet I am on and it makes sense their data shows with a 4 in gun and 124 FMJ at 6.2 grs 1243 so 5 inch gun at 7.2 should be were I am at.

    when I get this USPSA gun done I will put picture up but our machine work is NO Where as Elegant and Proffesional looking as your work, but it will be functional, whole idea is weight so it will serve its purpose. I don' know what you charge to lighten one up and make it just soooo nice but I have seen prices from 600 to 800 but I see guys all the time with those $3500 guns but I don't think any of them are retired like me.
