A very promising prototype on display at SHOT Show was an aftermarket Locking Block for Glock pistols designed by Strike Industries. This drop-in part promises to substantially increase accuracy of off-the-shelf Glocks. The Strike block has to two additional features that help lock the barrel and slide more securely than the original. First of all it has a rail on each side that works alongside the front and rear frame rails. Secondly it has a ridge to the rear of the block that engages the chamber block that prevents the barrel/chamber from moving around.

These two changes seem simple enough, but when I handed an original Glock and a modified Glock on the SHOT Show floor, I was very impressed at how much better the barrel/side lockup felt. The proof, of course, will be how well it shoots at the range. As soon as we can get them to send us one, we will do a range test and report back to you.
