I had nothing but problems when I first got mine, so much so that I put it away for 3 years. Dug it out a few weekends ago, didn't even bother to add any lube just figured it would jam up like always. I had the weaker recoil spring installed and managed to get off about 150 rounds of Velocitor, some Aguila hyper velocity, and the kicker....Remington Thunderbolts. Thunderbolts were the most accurate in the gun and didn't jam up until the very end. I think the lack of lube was what stopped the gun, I'd fire and the slide would stay back, not locked into position. Just had to tap it forward and it would chamber the next round just fine and fire. Decided to give it good cleaning and lube it with Mobil 1 grease on the slide,, guide rod, rails, part of the hammer the slide runs across and barrel. I've been using this KG moly dry lube on some of my other guns in areas where triggers and anything to do with the firing system, you brush it on and it dries. Got that in as many places as I possibly could on the Mosquito. I'm not going to say the trigger went from crap to some match grade trigger, but there was definitely a improved feel. Still a crap trigger pull though. Took it to the range today and out of 500 rounds there was 1 issue, a round didn't ignite. Put the round back in the mag in a different position for the firing pin and the round fired. Not one jam, hiccup, FTF, FTE, nothing other than the 1 round that didn't fire first time around (I'll blame the ammo on that one). all with Thunderbolts. I don't know if the gun just needed an extra long break in period, or if running it without lube fixed the issue or what. Just know that it works finally.
