I received today my new magwell made by Danny Woodard (Staudacher on this forum) and couldn't wait to get it on my Sig P226 X-5 Competition .40s&w. This is the gun I use in USPSA Limited. See attached pic.
After reading several posts by other Sig P226 X-5 members regarding this magwell, I ordered the Standard Magwell.
It's fantastic! The fit couldn't be any more exact. It fits incredibly snug, as it should, but doesn't require any special tools except a screwdriver. Slip the old one off, and slip the new one on (the new magwell takes some force, but nothing out of the ordinary). And, no work was needed on the grips. They fit right back on with out any issues.
The factory X-5 mags fit perfectly. The Mecgar standard P226 mags required just a bit more filing down of the sides to fit. I had to file them down a initially a little to get them to fit into the original factory magwell, and just a little more filing got them to fit into this magwell.
Danny, I'm really impressed! Your magwell looks great on my x-5, and it functions great, much better than the factory magwell.
