I received my Mosquito yesterday, with a pink finish. I shot 100 rounds through it at an indoor range this morning and I fell in love with it. Of course, first firing it you'll have one FTF, which is what happened with me, but this is one accurate little beast. It's real trigger heavy, but it doesn't take long to get used to. If .22 ammunition was easier to find I would be all over going to the range every single day. A good buy for a first time shooter like me.

I bought this pistol a couple of weeks ago, took it home cleaned and oiled the gun. I started by firing a hundred rounds of CCI through the gun with no problems at all. I changed over to Blazer, and fired another hundred rounds. Moved on to some Golden Bullet Remington, and fired another two hundred rounds of the bulk ammo through this pistol without any problems. The only real problem I have with the pistol is the trigger... it is pretty bad. Single action is poor, but double is gosh awful. The pistol shot nice groups from the bench, and sights were pretty easy to pick-up. All in all I was very impressed with this pistol, especially after many of the bad reviews I've read on feed, failure to feed, and other problems I've been hearing... Guess I may be lucky... IDK

This is a great little .22LR pistol. If you are going to get this gun keep these few things in mind.
1. Clean gun before you shoot for the first time, and keep it clean.
2. Use high quality/high Velocity ammo. (CCI mini mags)
3. Use the correct recoil spring.
4. Remember to hold the gun tight when you fire it.
Shot 250 rounds with this gun. (200 CCI mini mags / 50 Remington high velocity) Had 2 failures to fire, 1 failure to load, and 1 stovepipe jam. All of which I believe were the ammo's fault not the guns.

I bought one in August.
Ergonomics: The ergonomics are amazing, if felt like it was custom designed to fit my hand.
Construction: The slide had between 1/32-1/16 wobble side to side. The dealer said this was normal ??? I have never had a semi automatic with this much side to side wobble in the slide, and honestly, it made me a bit nervous.
Performance: There was at least one FTF and FTE sometimes 3-4 in almost every magazine. Had the feed ramp polished, AND kept it meticulously clean, but it still had problems.
I dont know if these problems are sporadic or if they are common. Regardless, a pistol with performance issues of this magnitude is useless IMO.
I would not recommend this pistol.

Single action, means it can be cocked and fired. Double action means it can be cocked or just squeeze the trigger with the hammer de-cocked. If you load the magazine, action the slide, a bullet will be loaded into the chamber, at which time the gun is loaded and ready to fire, with the hammer cocked (Single Action). You can de-cock the weapon at this time, and fire your first shot by squeezing the trigger (Double Action), or you can re-cock the hammer and shoot the pistol Single action... Either way each consecutive shot will automatically cycle the action and the pistol will be ready to fire again in single action, hammer cocked.
everyone says CCI but we just made sure the gun was cleaned very well and have used everything under the sun without issue. It seems to be shipped with white grease on the internals and you want to get that out before it gets hot and covers everything. My thought is that's the issue with picky ammo on this guy. We cleaned it all out before shooting and haven't had one issue yet.
This is a .22 LR it will not use Win Mag ammo. Most .22 caliber semi autos are ammo sensitive. While they may function perfectly well with most types of ammo there will generally be one brand that is superior to others, It is up to the owner to experiment until that round is determined, again this isn't a neccessity but it will increase accuracy and functioning.
