Sig Mosquito -- First Impressions
I just bought a Sig Mosquito despite the dire warnings from some about reliability issues. After approximately 350 rounds, I have had exactly two failures to feed properly, one failure to eject (stovepipe), and one failure to fire. For my purposes, strictly target practice, that is well within acceptable limits.
Before I ever fired the pistol, I read the owners manual, the maintenance manual and the Sig website faq's, and I tried to follow all the advice to the letter. I carefully cleaned the grease off, and oiled the pistol and magazine. I have only used CCI Mini-Mags (36 grain, 1260 fps) as Sig recommended. I added a drop of oil to the port on the slide after every 100 rounds. After each use, I thoroughly clean it.
Both of the failure to feed issues arose after I had added oil on the slide through the port. I wonder if I might have gummed things up by adding the oil. I looked at the round that did not fire, and there was an impression from the firing pin that looked normal, so it could have been a bad round. In any event, so far I am really pleased with the reliability of this pistol.
My main reason for purchasing this pistol is the cost of ammo. Obviously the .22 is a lot cheaper than my usual .40 caliber. Since the recoil is much lighter I also find that I become less fatigued shooting the .22. I am not the greatest shot, but I am able to hit 8 inch targets reliably at 50 feet, and my patterns are getting smaller with practice. I think the Sig is likely more accurate than I am.
I carry a Glock 23 .40 S&W. I originally became interested in the Mosquito because it is approximately the same size. Now that I have it, I actually find it more comfortable to hold than the Glock. It just seems to fit my medium-large sized hand really well. There may be a larger caliber Sig in my future.
