What's your perspective on the handling, size, quality, accuracy, etc.?

I had one. Real good gun, well made, good materials. One or two sharp edges out of the box but nothing 5 minutes with emory cloth didn't solve.

Reliability was good. Had a few FTFs in the first 50 rounds but after another 50 and a good clean and lube, I had no futher problems.

What I didn't like about the gun is despite its small size, it was heavy and a little wide. I bought it for something smaller and lighter than my Kimber Compact that I normally carry and it didn't really fill that need.

Not much fun to shoot, either. The short backstrap concentrates a lot of energy in a small portion of your hand - Corbons and Tritons are nasty; that said, it's not a recreational gun and it's a lot of power in a small package.

I did eventually sell it and got an STI LS40. That gun is thinner and carries better for me and being a single action and a near 1911, it's much closer in feel to my CCW and competition 1911s that I handle so much. The STI is significantly softer shooting too.

The MK40 is still a good gun though, if its what suites you. I wouldn't hesitate to recommend them to someone or even use one myself.

Thanks for the info stipilot! Right now I carry a S&W 5 shot .38 in my pocket, but am looking for something more powerful without giving up size to do it.  I know the Mk-40 weighs more than my S&W, but I like the size with the potency.  I would get it strictly for concealed carry purposes.  I have plenty of other pistols that are fun to shoot and handle so I won't feel too badly if the gun is not at the top of my "best handling" list.  My wife has a Kahr P9, but I'd like something even smaller.

STIpilot, please give us a full run-down on your LS40.  I heard there were some "reliability issues" after they first came out.

Thanks.  (got an SV myself :-)
