Got a mosquito as my first handgun. Picked it and my permit up on 2/28/13. That weekend, I took it to the range with 20+ year old CCI mini mags. It worked without a flaw thru the first 200. After that the slide got sluggish and I had a few fail to feeds, but it fired every round. I put a few drops of oil on the slide and it was better, but I called it a day t at 250 or so. I cleaned, oiled and greased and the next outing made about 250 before the slide thing happened again. Field stripped, wiped the rails, greased and back to flawless for another 200 or so. I've got nothing bad to say about this little gem. Ive shot a few Remington mags without a flaw, buzzed a few thunderbolts thru it. Trigger gets better the more I shoot it, sights are great. I shoot 4" groups at 7-10 yards and I can religiously put em on a 12" at 25 yards!
