In my search for a decent pistol that won't break the bank, I went to my local gun show yesterday and picked up a .22LR Mosquito. Reviews on these sound pretty good, but a few people have had jamming problems.

My gun is brand new in the case, hasn't been fired yet (at least not by me). Due to the ammo shortage from everyone stockpiling, I haven't been able to buy any yet, but this comes with an advantage. It means I can wait a little and get some advice from experienced owners like yourselves to help me find which brand/type these guns like best.

Any tips? Thanks!

CCI mini mags would be best for break in. 40 gr solids.

Just remember to clean and lube before shooting. I do this with all my new guns.

have fun, welcome from az.

Follow Mattylite (Sig's recommendations). Clean and lube before using. Stick with CCI Minimags. Folks that don't have the problems.

Keep the weapon clean, rimfires are messy rounds.

I just ordered a Sport model.
What is the recommended cleaning and lubrication options?
Thanks.

I have a sport model too. Same recommendations: clean and lube first. Use CCI Minimags and Milcomm TW25B grease (came with pistol). Keep her clean.

Thought the sport model was discontinued? I like it better than the base one.

Enjoy you new purchase and stay safe.

Once they become available after the mad dash to buy all the ammo possible, I'll find some Mini-Mags to put through it. Also, I saw a video up on Youtube of a guy filing and polishing the feed ramp to help prevent jamming, since there's a slight ledge on it where the ramp meets the chamber:

Is that fine for someone who's good with their hands to do, or is it best to leave it be?

EDIT: Also, question on the slide springs. It comes with two, one of which the manual claims is "marked white." Neither spring I have is white anywhere on them, but one is longer than the other, and the short one came installed with the gun. Which is which? O.o

Hopefully double-posting isn't against the rules. ^^; Couldn't find anything on that.

Anyway, I went out and bought a Dremel, since I've been wanting to get one for a while now, and this has given me a good excuse to buy one. Went ahead and filed down and polished the feed ramp, giving it a nice, smooth, curved transition, with nothing for the bullet to catch on, and then cleaned and lubed it up, so it's ready for use as soon as I find some ammo.

Here's a few pics:

My Mosquito is a jam-o-matic... However, with CCI Mini-mags, my Mosquito performs well... The more rounds I shoot through my Mosquito, it seems like it gets less ammo finicky - as long as it is high velocity 22 LR.

I've been looking around for higher capacity magazines, and can't seem to find any, so I decided I'd see if I could modify the magazine to hold a few more. Thankfully, they can come apart really easily, you just have to press down that button in the middle of the bottom plastic piece, then slide it off. Watch out, though, because the tab underneath it is under tension by the spring. Gonna take some time to see how it all goes together and what can be changed to hold a few more rounds.

My Mosquito shoots CCI Standard and Federal Gold Medal (#711b) great, suppressed or unsuppressed. However, CCI Subsonics dont run well because of the bullet shape. Granted mine is plenty broken in but it doesn't need exclusively high velocity stuff anymore. Yours should be the same way in time.

I agree that CCI Mini Mags are the best until your Mosquito gets to the same point as mine. Walther P22s like that ammo as well. I don't remember having many problems with Mini Mags in my Mosquito.

Using spent rounds to test-fit, it looks like I've added enough room to add 1-2 more rounds in. I used the Dremel cutting wheel to extend the slot for the pin to move further down, and clipped about 4 coils off the spring, but not too much so it still provides plenty of force to push the last round into the chamber. I was able to add an extra 1/2" of room in the magazine, but I don't think I could make any more room without a different spring and guide. If I could find some parts of old magazines that could fit, I could possibly extend the capacity to 15.

EDIT: Finally got a box of ammo. My boss had a box of Remington Thunderbolts laying around. My magazine successfully holds 12 rounds and doesn't seem to have any feeding issues.

I love CCI Mini Mags, great 22 ammo

Cani Lupine

I'd get them if I could find them! Also got a couple small boxes of Federal American Eagles from a co-worker in trade for a box of .22 birdshot. Tomorrow morning I'll swing by the local indoor range and find out how much a membership would cost, and try the Mosquito out for the first time!
