I ordered this product for the "on / off" switch missing from rear-activated Crimson Trace products. The front activation sounds like a good idea but in practice is hard to activate. If your finger pad hits just a little off center... no laser without squeezing unacceptably hard. Even though I couldn't return the product, I spent the money to replace the product with the CT-636, rear activated. MUCH BETTER! Crimson Trace is a GREAT company and makes great products. This would should be re-engineered or removed from the product line.
Pros: accuracy, looks, features
