Sig Mosquito design problems and fixes

Just my opinion here on why this gun does tend to jam. My camera sucks so it may be hard to see some of what I am showing you, but if you have one of these you can look at yours and see what I'm talking about.

Pardon me if I don't take advice from someone that pokes at a feed ramp with a knife blade.

@midnight7734 I know what I'm talking about and doing. The knife won't hurt anything. If you don't want my advice then that is fine. A lot of other people appreciate it.

Thank you for this video alot of good info. I just purchased a mosquito myself. Now due to this video if it acts up I know what to do to correct it. Thanks.

my sig has always worked flawless for me, R u a gunsmith? Use better ammo, do use cheap bulk ammo thats half your problem. Sig test fires 100rds thru every gun before it sends it out. I have a mosquito, 229r , 229sas, and a 220, never ever had one problem. Maybe I am bias because I like the quality of Sigs, you could of sent it into to them before you voided you warrenty. They would of fixed any problem you had.

Even Sig can screw up. I have a Sig P228 and it is extremely reliable. There is no reason to do all the things you have done to make your Mosquito work properly if the gun was made right from the start. I have fired a friends Mosquito and it has a terrible gritty trigger. Also the slide is made from zinc and I have heard of many slide failures due to breakage.Some people might like theirs but I think it is a crappy gun.

@wysoft Cool man. Thanks for all the info.

I forgot to mention. Another part that requires this treatment is the hammer strut where the hammer spring rides. It also has very sharp edges and a rough face, and will contribute to grittiness of the double-action pull.

Also, you can lighten the trigger just a hair by removing the brass washer that rides on the bottom of the hammer spring. It's not by much, but it seems to help.
