If there's a more technical designation, I didn't get it. These .22 LR semiautos are on sale locally for about $30 off, so $370 new in box. Never came across one before, so does anyone have experience with them? No harm in my having something that isn't a strike fire to practice on and I'm told these aren't- but of course the store had a trigger lock on the one I looked at which left me with little to go on.
 
They’re also tiny so hopefully you have small girly hands.

Actually a plus, especially if the goal is young/new shooters.


Having guys come on and call it junk, is like the HK guys bashing Keltec at every opportunity (how's the view from up there? :p)

You get what you pay for. IMo, at $300 or under, it's a great deal.


It tends to be finnicky about ammo (golden bullets cycled as well for mine, as any other .22 I've shot/owned), and the slide apparently can fail/crack around 10 000 rounds. (I wish I had the time to do that much shooting. I don't think I've fired 10k .22 rounds in my whole life)

I just bought a new GSG, and I liked the quality and feel of the mosquito much better. The GSG feels like a poorly made toy, while the Sig actually felt like a properly made firearm.


-slide issue
-picky about ammo
-no/little resale value, due to it's bad rep.

You get what you pay for. If I saw one in decent shape, selling for $250, I'd snatch it up in a second. I think there are much better .22 pistols, selling for competitive prices now though, that anything over $300, isn't much of a deal.

my 0.03
 
I put just under 10,000 rounds through one before I racked the slide and my hand just kept going.

My bigger issue was with the springs (trigger springs, etc.) breaking. My trigger went dead twice. The second time, I just gave up on it.

But... I actually really liked it. I shot the hell out of that thing for a couple of years. And... 10,000 rounds. I don't expect much from most 22LR semi-auto pistols, so I was happy with it. At about $300, it's not a terrible investment - if you like the style and the experience of shooting it. But, it's no heirloom you're going to pass down to your grandkids.

Pot metal junk. Generally speaking, guns made with zinc alloy major components are not quality guns.

The .22LR version of the P226 is a better choice.
 
If your looking for a "little combat trainer" .22, I'd recommend the S&W M&P .22 instead. Buddy at my club says his mosquito is a jammo-matic.

The M&P is probably the best 22LR semi around. I've owned just about every one, and it's the best.
 
I'm personally very happy with the P226 22LR. Uses a standard frame so you can convert it to 9mm/40 down the road with an x-change kit and if you want to invest in the platform you can upgrade the trigger and whatnot.

Btw, I was in the same boat as you and almost purchased a Mosquito.
Posted a thread in this forum a couple of months back.
Was guided to far away from the Mosquito/SA22 since they are hit and miss, mainly miss, reliability and durability wise.
I was advised to look at .22LR handguns that have been designed for the round from the get go.
At the time, Tenda had the SW22 for $380. Excellent gun all around.
Ruger and S&W make very good semi autos in both target and practical formats.
Browning has the excellent Buckmark as well.
Shop around and gorge yourself in YouTube vids.
My next .22LR handgun will likely be S&W M&P22 once the 2.0 versions come out.

Well if you're talking about a standard operating semi auto, then yes I agree. But overall the best out of the box production .22s are any of the Ruger Mark series, ie as in a Mark 1 or later. I speak as an owner of both makes.
 
I've wondered why the GSG made Mosquito slides had major failures, but the GSG 1911 .22's don't have that bad reputation.

Is it that GSG made changes to the material they use in their slides, or is it a something else?

I have occasionally thought about about getting one of their 1911's, but have held back because of the Mosquito issues.

No longer built, but High Standard over Ruger for me any day. More accurate out of the box better triggers, and way easier to strip. I have two.
