--- Quote from: Randy A on November 29, 2008, 12:19:28 AM ---Sigma, how does the Sigma compare to S&W's M&P models?
Very reasonable price tag.
A comparison test would be of interest.
Are there any options for the trigger pull weight?
Is this a striker type firing system?

How is it still performing? I have been thinking about picking one up.... The last time i went shopping I ended up with a Glock 19 ;D

Randy:
The Sigma was introduced in 1994 in the Sigma 40 version followed by the 9mm. It was basically a "knock off" of the Glock and intended to be Smith's answer to same.
In fact Glock eventually filed a lawsuit against S&W for patent infringement. Smith ended up changing the trigger system to avoid patent issues with Glock.
The original versions did develop a reputation for a stiff trigger and some feeding/ejection problems. Smith changed the original design in 1999 by shortening the barrel and slide, adding an accessory rail, and more importantly, enlarging the ejection port.
Sigma and SW99 pistols were good guns, the M&P introduced in fall 2005 is better.

Not to be confused with Smith and Wesson Military and Police Model 10 revolver developed in 1899.

VoooDoo69,

I purchased a new spring from Wolf Springs and put it in my Sigma. I think it reduced the pull to around 6 lbs. You can ordered them directly from their website or you can buy them from Midway USA.

I own both a Sigma and an M&P40. Two totally different weapons systems. The Sigma's trigger is very similar in weight to a DA revolver. Not quite as smooth as S&W triggers should be but after you put about 1k rounds through the gun it smoothes up and lightens a bit. It's really not an issue except for those who make it one. The M&P is a fantastic weapon. Alot of law enforcement agencies have switched over to the system including the one I work for. I started with my current P.D. being required to carry a Glock 22 and we just transitioned to the M&P40. I like the S&W much better. The grip is much more comfortable and natural feeling, the trigger pull is very good and seems to be getting better as the round count is going up. I don't understand some of the bad feelings towards S&W pistols. I've carried S&W since starting in law enforcement back in the early 90's and I always felt I carried one of the best quality firearms available. I've never had to use S&W to fix any of my guns but from what I read on the S&W forums is that their customer service is hard to beat. I have ordered a few items from them and they are very helpful. They will have my business for a long time to come.
