Mec Gar Plus 2 extension For M&P Compact.

[KentuckyWindage]

Well I wanted to put some info on these out there since there is little about them. I received two Mecgar plus 2 extension from G&R. These are for the full size guns but will work for the compacts also in 9mm, 40s&w, .357 sig. I am completely happy with the end product. I added two rounds of 40 S&W while keeping the same size as the factory finger extension. If I had a 9mm I feel that the extension would give you 3 extra rounds. The mag extensions fit perfect, drop free and lock the slide back 100% of the time so far with factory springs. They match the grip of the gun very close but just a tad bit off. Range test yesterday included 146 rounds. They were each 100% with Federal 96 rounds of 180 grain walmart ammo, and 50 speer gold dot HP 180 grain. Hope this helps anyone interested in these extensions. Thank you Grant!

Is it just an extension or does it include a new mag spring? I've always wondered about the long term durability of mag extensions and their effect on the magazine spring with constant use.

No, only the extension. I have also wondered that. I will have to see. I replace my springs yearly, so I will see if I find any problems by then.

Is there any trick to installing these on the magazine?

I just got a new 9c magazine and extension from G&R, but so far I can't get more than 12 rounds in the magazine unless I slide the baseplate forward by about a 1/4 inch, which is obviously not secure.

Thanks for the review. I've had my eye on these and was wondering about how they work. I was suspicious because of my percieved lack of interest.
Please update us as you go if you don't mind.
