This has worked flawlessly for me. I do notice compared to a dedicated 9mm colt mag lower, the locking mechanism is not as tactile as I'd like (the click into place is much more subtle with this), but it locked the bolt back and feeds VERY reliably. Thanks!

Wanted the bolt hold open & it has it.

Best block for the money, bought one tried it and was impressed, so I ordered one more again perfection. I ordered one more and built a 4 inch shorty, What fun. They all work well.
