I've been eyeing the Mech Techs ever since I saw one in person, and now that they're available for Glocks, a G17 model with extended mags or a G20 model sounds appealing.

Any reviews on these units?

My Dad bought one for my Glock 35.

Makes the Glock more accurate out to 75 yards and 100.  But your groups at 100 yards are pretty big.

I have a Trijicon Reflex sight mounted, and with 29 round .40 mags it is a fun carbine.

The only thing I dislike about the upper is the length of pull. The stock seems a little long for me, and I am average height. Also, the stock vibrates when you shoot, kind of sounds like a tunning fork.

There have been some guys here that have modified the stock to use a AR M4 stock. (Just like every other non AR firearm)

I'll have to check up on the refit of a stock, 'cause I'm reasonably tall.

Does anybody make extended mags for the 10mm?
