    I have an oppertunity to get a great buy on a sig p239 in either 357 sig or 40s&w. Is there a big difference in performance and recoil between 357sig and 40s&w? I have shot the 40s&w but not the 357sig. Other than the price difference between the two rounds can anybody help me decide which to go with. I realize the barrels can be swapped if I were to chose in the future but I guess I'm asking if the price difference for the 357 round is worth it. Also I have only been able to shoot the regular da/sa, any input on the DAK trigger? I liked the da/sa. This will eventually be a carry weapon primarily. Any help would be appreciated.

    .357 SIG is awesome. I shoot the Glock 32 and love it. The biggest difference I know of is that .357 SIG will shoot much tighter. Groups will be very nice. I had once a G27 and it was a tough shoot. Though it was the compact model. IMO, the think the .357 is a much better shot.
    The DAK trigger is awesome. I have shot it and really liked it. It's like not to hard or to easy to pull. Would love to have that Sig in that .357. Good luck

    I have both 357 sig and 40 S&W in 2 different sig 229s. Both are great, but the 357 will literally shoot circles around a 40. The 357 ballistics are awesome, and will hit distance(I've shot my Glock 32 out to 100 yards and put 10 out of 13 center mass). You can use the same mags for both rounds, you can do a barrel swap on the same slide and frame.

    If you're only gonna do one, go 40 cause 357 sig is pricey, but if you got deep pockets go 357 hands down. Texas Rangers and DPS use it for a reason, it's good.

    On the DAK trigger, that is personal choice. It feels a lot like a DA revolver, it's so/so in my opinion. I had a para DA that I did not like. I like traditional DA/SA better, but that's my opinion. I've never shot a 239 but the my experience with Sigs has been good. I have a 229 duo tone in 357 sig, 229 elite in 40 S&W, and a 220 carry. Accurate and reliable all day. If you ask me, I'd say thumbs up.

    Like AznZOhAn said you can buy it in 40 and buy a spare barrel in 357sig and you have both guns I did it with my 226 and love the versatility, although I mostly use the 357Sig for CCW.

    Thanks for the input. I think the best way to go might be 40s&w until I feel more comfortable with the gun itself then look into the barrel swap for the better ballistics of the 357. I'm still up in the air over the trigger choice... it seems some guys like the DAK and some don't really care for it. Might just go with what I know I already like in the sa/da. Thanks again for the help.

    One more word of advice, every 40 I've ever shot has alway shot low and left with the sight being centered from the factory, so it will adjusting. Every 357 sig I've shot was dead on from the factory with the sights centered. If it were me instead of just a barrel swap, I would get a separate slide assembly from Sig with the caliber exchange. That would save you head ache of having to readjust your sights. For a CCW I would go 40, and use the 357 sig for road trips. Texas highway patrol uses 357 sig because it has awesome ballistics against a car. It has the least windshield deflection, and penetrates the A frame on the car. The test was against other semi auto rounds.

    357sig is a ballistically outstanding round, but just really expensive to feed at the range. You'll be hard pressed to get it much cheaper than $20 per box (50). The best deals I've seen online are Georgia Arms $16/50 and American Eagle ($18/50), but both hit that $20 mark when you add shipping. Compare that to about $15/50 for 40sw at your local Walmart.

    I like the P239 a lot and wouldn't mind adding one in 357/40. The version I would choose would definitely be the SAS edition with SRT (short reset trigger). I'd make for a nice carry gun.

    Thanks again for the well detailed advice. I like the sas edition as well. I can't wait to get my hands on this gun and send some rounds down range.

    Secret service carries 357 for a reason. Flattest shot there is imo. 40 is slightly cheaper to shoot and the snap seems to be the same. I personally carry 40, but out of convenience factors...

    For my own tastes, 357sig/40sw both take a backseat to 9mm and 45acp. But that doesn't mean they aren't fine options for a lot of people.

    I do like the 357sig as a defense caliber. And my nightstand gun is a P226 chambered in 357sig. But this is something worth your consideration:

    A 40sw is cheaper to shoot at the range, more versatile in weight (135-140gr, 155-165gr, 180gr), and the lighter 135-140 CorBon defense loads are actually very comparable ballistically to 357sig. Maybe they're not technically as ultra-precise in a slow-fire range session, but you're not exactly calmly "shooting for groups" in a defense situation.

    Recoil is quite similar between the two rounds. I actually like the 357sig, but find 40sw to be a far more practical choice for the average shooter.

    being that it is highly unlikely I will be shooting through windshields or a-pillars as well as the price and variety of options with the 40sw my new 239 will be the 40sw. I will look forward to adding the 357sig barrel in the future.

    if you're going to barrel swap you can only go down in cal. it might take some research but I think you need the .357 and then pop in the .40. I don't know with the .40 will take a .357 barrel.

    Hope this helps or if you already knew all this maybe it'll help someone eles

    Going from 40sw to 357sig would be "going down" in caliber...not the other way around. A 357sig is a 40sw case necked down to meet a 9mm bullet. If the 357 was larger, it (obviously) wouldn't have any need to be "necked down". That's why 357sig's standard weight is 125gr, while 40sw's is 180. A 357sig shoots a 9mm bullet, while a 40sw essentially shoots a 10mm.

    Regardless, you can (in almost all cases) go either way on these calibers when it comes to conversion barrels and bi-caliber mags...because the butt end (70% or so) of the 40sw casing applies to both.


    I don't mean to be rude at all, but... DodgerBlue, I'm going to excercise an opportunity to call you out a bit here- based on some of your previous posts claiming that Glocks are the be all/end all...and that archaic guns like the BHP can't hold a candle to them. Well, your limited experience is now officially confirmed. Glocks are very good and very reliable guns BTW, and I wish you nothing but the best in your experiences with them. But you have a great deal to learn. I should know, as I'm in that boat myself. But maybe keep a bit more of a humble, open-minded approach going forward.

    Good choice, enjoy it. Sigs are good guns, I have 4.

    You need more experience dodger, but don't take it personal. 40S&W kicks less than the 357sig which means more manageable, the 357 is a smaller and lighter bullet, but it has more power. My advice is start with a 40 then convert to 357, because we walk before we run and 40 is slower than 357. I have a Sig 229 in both calibers and I'd say start 40 then move up because of price of ammo and manageability.

    Going from 40 to 357 is only a step down in physical size, it's comparing a middle weight boxer to Bruce Lee. You don't mess with either one, but if you did you mess with the slower and weaker boxer before you tangle with pure power and speed. Look at this pic of 357 sig ammo, the ballistics at 50 yards is better most 40 muzzle ballistics. 357 sig is hardly a step down.

    In my experience I wouldn't agree with this at all. I've found that they handle almost identically. But my only experience (shooting both through the same gun, that is) is with a Sig P226. So I've only done so with a full-framed, well-balanced, and somewhat heavy gun. Maybe that's skewed my take. I honestly don't know how a lighter frame like a compact Glock would handle one vs the other.

    As far as ballistics and defense...the larger diameter of the 40sw will make a bigger hole. The 357sig's speed will deliver more energy and a flatter trajectory. The lighter 135-140gr 40sw defense rounds will offer many of the best attributes of both rounds.

    When it comes to the subject of "conversion", going "up vs. down" is almost exclusively dictated by bullet diameter. So you're converting down to 357sig from the larger diameter 40sw.

    And I'll still usually turn to 9mm or 45acp as my autos of choice.

    You're right diameter has a big advantage, but bullet design has alot to play in also. If you compare 357 sig corbon to 40 Speer gold dot, the corbon blows a bigger hole. And if you hog hunt a 357 sig is a lot better back up gun than a 40.

    I have a G23 and had a G32, and on that light frame you feel that difference. And if you're compare a light load 40 do the same with the 357Sig(apples to apples). My experience is limited to 15 years and my collection is small by some standards, but I own no garbage. I've shot everything from 22 to Smith 500 in handguns. Not a lot but but I got some experience.

    I like both rounds and they have their specific jobs.
