Is the sig sauer mosquito a good plinker with a red dot sight for competitionshooting?

Question

for competition shooting

Answer 1

I'd say its a good plinker, red dots are always fun on a plinker but I personally don't care for the way they mount on the mosquito.  to be honest my ruger 22/45 kicks the c**p out of my mosquito sport, the ruger is a lot more accurate and I can't recall it ever having any failures at all and I've put thousands of rounds through it (I'd guess about 8000) not to mention its at least $100 cheaper, my mosquito is picky about ammo and has about 3-5 failures (to fire or feed) every 100 rounds and its a newer model that's supposed to be better (apparently serial #'s a042xxx and back didn't like anything but cci mini-mags or hotter ammo).  the mosquito however feels a lot like my p220 and p226 it even fits in the same kydex holsters and its a lot cheaper to shoot, I just wish it was up to the quality that I expect from sig.

I wouldn't even consider it for serious comp. shooting, the trigger just isn't good enough and there's really no aftermarket fixes for its short comings, if you want a decent affordable gun that can be built into a comp. grade pistol then get a ruger (mark II/mark III, 22/45) or browning buckmark.  its still a lot of fun though.

Answer 2

The Mosquito is a good combat shooting trainer.  It can be fairly accurate but in no way is it a target pistol for competition shooting.  The newer versions are more reliable the those made a year or more ago.  The red dot that comes with the mount is not bright enough to use in full sun light.  It does work well for indoor ranges and on over cast days.  A scope would be a better choice.  Even resting the pistol butt on a bench and using a scope I have never gotten better than 10 rounds in less than a 3/4" group with one.  You can do better with the Browning, Rugger or even a Beretta Neos.  The trigger is not good for competition since the single action pull is about 5 lb or more actual and above 12 lbs on double action.  Target pistols normally have 2.5 lb pull or less.  The elevation is adjusted by replacing the front post.  There is no elevation adjustment on the rear sight.  I shoot mine a lot and enjoy it as well.  For practice drills and just blasting away it is a great gun.  With Mini-mags I have had one fail to fire in the last 4000 rounds and maybe one fail to enter.  Cheaper ammo does sometimes need a second strike to make it go off and other possible ammo related problems.  Shooting with the heavy trigger pull has an advantage.  When you switch to another gun with a lighter trigger you will shoot better at least I do.
