If you own a metric *** ton of CCI mini mags or have no problem buying this "premium" brand of 22 ammo, then you should be fine. If not, well then get used to clearing jams.
Got one for the wife to plink with and I have feeding issues with it all the time. Almost never ejects the casing completely or will double feed. I have tried all the different ammo out there too. Issues left and right with it but the feeding is the biggest. That and the mags are $30-$45 a piece. When it actually works then its pretty fun but when it doesnt it just causes problems.
Guess I got the only good one. I love mine put all kinds of junk 22 through it and never had a jam. With the threaded barrel and suppressor it is one of my most fun guns to shoot. Rugers are great also,cant go wrong with them.
Had a Sig, and shot it next to a Ruger MKII, both never had any probs w/ ammo ( I dont rember what we were shooting in both guns, but it was def. cheep ammo) I do rember that the Ruger MK II shot much better groups than the Sig. I really want to try my bare bones MKII aginst a M&P 22 pistol. Anyway go w/ a MKII Ruger or a M&P 22 pistol.
I use my mosquito for a paperweight, it does a much better job at that than as a reliable autoloader. I get anywhere from a 10 to 30% jam rate with it.
I like mine I have put 150 rounds though it you need 40 gram ammo or it will jam. Its still cheaper to shoot then my 9mm. And hell the way I have seen them selling on here you can get your $ back if you don't like it...
