Just got hung up on because I was venting a little about the Sig Mosquito. Mine only shoot one kink of ammo. The high priced mini-mags HP. I've had alot of guns over my 52 years and this one is the most frustrating because of the quality I expected from Sig and the money I spent. I've watched all the videos of polishing the ramp, the lip on the barrel, using t right spring and it's ammo pickey. But Sig should send a recall on them just to save their reputation. The customer service department are so defensive over this gun, they're mad before you start talking about it. I've bought my last sig from them. If sig is so good, why can't they stand behind their guns. They will stand behind it one year from purchase date. Most blog I've read, the guns come back wit the problems. That's why you see youtube stuff on how to get them to shoot halfway reliably. Sig Mosquito is a bad weapon for the money. And if you wanta get really pissed call their customer service. They're worse than the gun.
