EASILY a five star rating. Get a quality tap handle, use a little bit of some household 3-in-1 oil to help the process, take your time, go slow, think before you act, and success with this product is pretty much guaranteed. This was the first time in my live I've ever tapped new threads, and it went easy as pie.



I had a stuck and buggered up grip screw bushing on my Springfield M1911. I had previously tried turning it out with a screwdriver, which naturally failed, and drilling it out to collapse it in on itself with a punch, which naturally failed as well. I was left with the original, and now damaged, threads in the frame, together with remnants of the grip screw bushing stuck in those threads.



I spent about 20 minutes slowly and carefully working the tap into the hole, with the help of the alignment jig. As soon as it was ready to cut new threads the tap bit and the feeling on the tap handle changed. Just a few easy moments of carefully tapping the new threads and presto, my oversize bushing fits perfectly. I'll be replacing the other three bushings with the higher quality hex-drive versions, BEFORE they cause problems.

Brian and ALL his products are top notch and recommend them to all that need Grips /Bushings/screws and Tools. Great Guy to Deal with and will get all my business

I normally dont leave reviews but was so blown away with the quality of the Challis products I had to say something. My son bought a brand new Kimber custom LW pistol on Tuesday and when we were disassembling it we found that 2 of the grip bushings were stripped from the factory. Not wanting to deal with Kimber customer service and the wait times that go with it. I went ahead and ordered a set of oversized bushings, tap, and tap guide from Challis. Ordered on Wed and at my door Sat. The Challis tap did an amazing job of cutting and tapping some of the most beautiful threads I've ever seen. Everything turned out perfectly. Great job Challis amazing products fast shipping. Thank you for providing quality products to make a bad situation perfect. Thank you again...Jeff

Easiest fix I can think of. Worked beyond expectation.

The tap started easily and cut through the aluminum frame quickly. I should have used some kind of guide to keep tap perpendicular to frame. The job still came out okay.
