I had a particular use case that I used the shell deflector part for and thought I’d share. I have a california-legal sub 2k (gen 2, 9mm glock 17). This means I have a zytel grip fin around the grip and extending back towards the receiver tube, in order that my shooting hand thumb cannot wrap around the grip with all the evil, antisocial behaviors doing so would enable (cue sarcasm emoji). You guys outside CA and NJ etc may not even know what this is but if curious you can google “featureless grip fin”. It’s a really awkward and illogical means of addressing the messed up CA definition of assault rifle. But i digress…
The fin leaves you needing to find a place to put your thumb while shooting (not to mention charging the rifle), and the ergos of the sub 2k complicate this. You end up having to put your shooting hand thumb right up against the rear of the ejection port if you want anything like a normal rifle grip, and while there’s a nice polymer ridge that frames the port, it puts a body part (thumb) a little closer to brass and gas forces than I’m comfortable with. It’s not like a glove and some caution won’t avoid problems, but I was looking for both a measure of additional protection as well as some additional support for the awkward thumb ergo required by the grip fin.
So I got the shell deflector part and, not being a lefty, proceeded to modify it for my circumstance. I’m sure if I was a lefty I would have simply installed it as intended, but as it is I felt it looked weird and too different than the stock design of the rifle. So I fiddled with it and imagined a design that would do what I needed and found that I could use the oven and some snips to start forming the “thumb guard.” I pretty much didn’t use 80% of the part…Assuming the adhesive I used holds and all else works out, I think I have what I want. Hope that might provide an idea for those who have to use grip fins
