Last month we picked up a Sig Mosquito as our first gun in the home. I opted for it after doing lots of reading... because I wanted a gun to train on... and I felt that enough adjustments had been made since some early issues that it would serve my needs even if the early reputation could not be shaken off in some minds. I have posted some of this in other threads.. but wanted to do a standalone summary What I like: I like the design of the controls (I see a 226-229 of some kind in our future in 9mm) I like how it feels over the other guns we looked at like the SR22 I like that it is pretty predicable..There are things I can do to make it run nearly problem free.. and things I can do that will tend to force an error.. which clearing is a good drill for me. What about Ammo.. I was lucky enough to find some new stock of CCI Mini Mags locally for 16 cents a round so the first 400 rounds were with the recommended Ammo. About one rnd per 1-2 boxs fails to fire .. rotate it in the magazine and it works.. so I attribute that to the ammo. When I was a bit rushed in loading the mags.. the 2nd round would sometimes fail to feed, but only about 3 times before I figured it out. I have never had a failure to eject with fresh CCI Minimags using the high velocity (standard spring) nor with the lower velocity spring. And now that I have mastered loading the magazines well they pretty much always work.. but I only have 100 rounds of them left so don't take them to the range... Recently I bought almost 1700 rounds of 1971 vintage CCI Minimags... they have worked for the most part. On the standard spring I do get some failure to ejects and in shooting can feel the vintage ammo has a bit more variability in power.. Moving to the lower velocity springs the Vintage CCI Minimages will run 100+ rounds with no flaws.. but then I might hit 20 with 2-3 feed based failures..Nothing that gets in the way of my enjoyment of the gun or shooting.. and since I only paid .10 cents a round for the vintage stuff I am pretty happy. in loading the mags I note that some of the round's brass might be a bit snug... QA at the time or age I don't know.. The surprise this weekend was some Remington Golden Bullets I paid about 16 cents a round for.. off Gun Broker.. I wanted to have a HP round for home protection since we only have a 22LR. I think they are 2 years old.. before the "New" was added to the box.. I shot 120 rounds today trying with both springs . not one failure to fire.. not one jam.. When things settle down price wise to more normal I hope.. I might end up using these the most. And will be very comfortable with them being in the loaded mag I now keep in the safe next to the gun. I like the gun... It may be a bit more fussy than some others.. but I have to say it feels very accurate.. I am 49 with a bit of a shake in my hands that I have always had ...and am pretty new.. and yet I am finding that shooting next to others who clearly have more experience.. using larger caliber guns.. my groupings are often tighter... which surprised me.. 5-6 inches in some cases for 10-20 rounds a 7 yards. I also would note that again today there were people having jamming problems much more often than I did.. What's my gun care regime: I have standardized on Milcom TW25B Grease and Oil.. I clean it after each trip to the range where I shoot 200-300 rounds a visit. I am enjoying the new education and practice.... and am very satisfied with the Sig Mosquito.. it is responding exactly like I expected..
