The SIGMA is a very fine handgun, but IMHO has been misunderstood by a lot of folks in the shooting community. I've seen on this forum stated that if one was a revolver shooter then the SIGMA trigger would not be a problem and I agree with that. The wife wanted a .40 S&W, she has small hands, the SIGMA fit. I have previously posted her response after shooting the gun for the first time, but it bears repeating, something along the lines of "triggers a little heavy but otherwise no problem". Keeping in mind we're both over 55 and have been shooting revolvers most of our lives. I would not want to stand within 50 yards of the wife and have here shoot at me with the SIGMA.
In this day and age most folks want something right now, right here, their way. Kinda like McDonalds/Burger King and don't want or maybe don't have the time to learn something new…oh well their loss I guess.
I cast and load cartridges for the SIGMA, shoots whatever I put down it with no problems, no feeding/ejecting problems, kinda like the Eveready bunny it just keeps on going.
Could it have some improvements, sure what's made these days that doesn't? Just look at the auto industry or any other and count the number of recalls.
So that's my opinion, yours may be different and I respect that.
