Anyone that's thinking about a drop-in(self installed) Magwell w/ backstrap might what to check opt the Stan Chen SI Magwell. His website. I can attest that the workmanship is second to none and they fit perfect on Springer's and DW's. I've installed 4. Blue and stainless. And the price is right. I've heard that on Les Baer's the frame is a different an fitting is required.
