Things I liked:Installs easily, improves accuracy, looks good, and durable. Things I would have changed:Maybe add some shim material. Leaves a slight bit of play easily remedied. I put some electrical tape around the frame before sliding on the stock. Trimmed off excess with utility knife, cannot notice the tape and snugged up the fit perfectly with no play. What others should know:Works great with the reversible peep sight on the guns with that feature (1377/1322/2240).
