Also, I have some Mec-Gar P18 mags (The kind that Dawson says won't work with their basepads) - and just for fun I slapped a Dawson basepad on it.

As promised, it was not able to fit into my Rock TCM/9mm

Out of sheer curiosity I dropped it into my .45 RIA (pictured above) and it fit perfectly. The mag locked into place, and the slide release went up when I brought the slide back.

The magwell on my 2011 M1911A2 45 is higher cut into the frame of the pistol, where as my TCM/9mm is not.

We'll see if this combo actually works in the 51679 when I get it.

My local gun shop was able to find one and ordered it for me. I have been reading the posts here about the mags. Once I get my pistol I will start looking for mags. You guys have posted some very good information on this subject. Keep it up. B)

I tried all week calling armscor to ask about a 40cal with no answer left a message but never got a return call

Are you looking for the #51738 or 51782?

I found the 51738 pro model Tombstone tactical

I wonder what the difference is (besides the significant price difference) between 51738 and 51782? I can't find 51738 on the RIA website but is shown at the Tombstone website you sited and it is also shown on the Gallery of Guns website. Anyone know the answer?

I did get my hands on a 9mm RIA 2011 Hi-Cap (the TCM/9MM) and it works great. Dawson's great mag extensions do fit with Mec-Gar P18 magazines - in fact they fed fine with the standard magazine spring. I think I need to get a liner for the mag extension, as the follower did bind once I got past 19 rounds in the magazine.

Just an update on my RIA that i sent back.

The sent me a brand new pistol- the tcm/9mm target model which is great with me.

I prefer those sights anyway.

Ran it in two matches this weekend and no complaints. I do prefer a 10lb recoil spring though.

no idea what the stock one is.

Of course, one of the STI mags I fitted to the old pistol does not work now. No blame to armscor there.

I have several tcm/9mm mags fitted with dawsons length not capacity extensions that no longer fit either.

*update- I took the dawson .0200 basepads off the mecgar mags to see how much lack of clearance was. there was definitely enough room with the mag inserted for basepads.

A bit of filing and they fit. As this is the Target model, I have a dawson magwell and that still fits so I wanted to use it.

I ordered a few Para mags and I have another STI to modify later.

Big thanks to Amrscor.
