CowCow Technology Match Grade T01 Magwell for TM Hi-Capa Pistols (Color: Black)

"I purchased the rainbow version and I'm satisfied. It may fit loose at first and standard length mags may not fit, but a small rubber strip is included for fitment and silver TM mags fit fine.

"This magwell is constructed nicely. It fits wery well on both my tm grip s well as my am omnivore. I aso had the issue where standard mags do not fit anymore though. The answer i found to this is the stock TM 5.1 mags that have the longer valve base, combined with the WE tech low profile baseplate fit perfectly. Also, the longer aw mag that comes with the john wick combat master fits too. Other mags work with no baseplate if you really dont care though. That said... it is annoying, but the magwell is sexy looking and really provides a smooth reload when the magazine is configured the right way to fit.

"Out of the box on two seperate Hi capas I own, this magwell fails to let the magazine reach the mag catch and actually drops the mag on a reload. This means you cannot insert a magazine with this magwell unless you do some filing.
