Recently picked up a RIA Tac Ultra High Capacity in .45 ACP for less than $700. Considered a Witness or SAR, but parts for a 1911 are a lot easier to find and supposedly RIA has a lifetime warranty.
I am using Mecgar P14 mags and they seem to be doing fine. RIA supplied one. I was wondering if any one knows whether the Wolff +10% Para Ordinance Mag springs will work with the 14-round Mecgars. I'll order one to try, I just don't like to waste shipping on small orders for T&E.
Figured on of the knowledgeable people on this forum may have peeled this onion before. Also curious if anyone has any experience/recommendations for any + # extended bases that meet USPSA rules. The Mecgars sit below the magwell. Locking a full-mag on a closed slide may cause issues during a competition. I think Dawson makes some extended ones that I think will work with the tube but they don't add any capacity.
I only have 70 rounds through it but am genuinely surprised at fit and finish. Extractor is tuned well. I am have a failure to lock-back issue, but I suspect there is debris or a bur in the plunger channel. Worked initially. May just need to work it some more. RIA scribed the takedown lever so the detent/plunger locks into it rather well. Better that than locking back when it isn't supposed to. Ramped barrel and the sights are fully adjustable. More testing this weekend.
The only negative I have is that RIA apparently submerged in a barrel of 90W gear oil before shipping....
