    I wanted an extended magwell for my Tisas stainless steel Duty in 45ACP. I didn't want a magwell only because I didn't want to grind out the necessary spaces in my G10 grips. This magwell/mainspring housing was a perfect match. Fit and finish was exceptional. It was very easy to install as well. No final fitting modifications were needed. It just dropped right in. It functions very well, and the price was outstanding. Definitely a quality product!

    Tisas 1911 Magazine well w/ mainspring housing, stainless

    Very pleased with the magazine well mainspring housing. Installed this on my carry stainless 45 cal tisas and it looks Great. Fit and finish is top notch and my pistol looks like it came from factory that way. Thinking about one for my D10 now but will probably wait to see if they offer the grips that come on the 1911 match.

    What the D10 should have come with

    Posted by William on 23rd Dec 2023

    This went on my latest acquisition a D10. I was so impressed with the match had to have the D10 in 10mm. Was disappointed that it didn’t come with the Magwell of the match though. Bought this one since the one on the match seemed well made. No fitting was needed (keep in mind that it isn’t “blended” into the frame, but is fits just like the match). Someone earlier mentioned the hammer spring and plunger was already in the one they received. Mine didn’t come that way, but no big deal. I just swapped over the parts from the D10. I tried to order the grips for the match but didn’t see them on the Tisas web site catalog. Ordered much more grippy G10 ones from VZ grips. I highly recommend this magwell mainspring housing.

    Can't beat this mag well for the money!

    Posted by Greg Swift on 23rd Nov 2023

    Recently ordered this mag well for my new Tisas D-10 10mm. At this low price, figured it would be a 2 piece unit. To my surprise, this is a one piece mag well. If you check prices online, most other retailers are selling them for at least twice this price and even higher. I was very excited to get this mag well and it's beautiful in it's construction and finish. Very happy with this purchase!

    Superb quality and fit

    Purchased this for my stainless “Duty” 5” Tisas in 45acp. Fits perfectly. Quality is exemplary. This one came complete with all internal parts that one has to typically purchase separately. Would very much want one in black for my Tisas B9 in black cerakote which, by the way, is a superior 1911 just like the stainless “Duty” is.
