The Tape Test

[4 Scale]

From time to time people post photos of very hard inside strikes that have damaged the striker guide, rear of the breech bolt or both. In my collection, some frames show clear evidence of the striker guide hitting the frame, others show none.

On my pistols with evidence of striker guide hitting the frame rear, the striker guides are not marked so I'm guessing it occurred in the past.

I frankly do not understand how striker guide impact to the frame relates to or interfaces with the toggle duckbill strike to the frame. I am hoping someone with knowledge will comment.

Both strikes happen at the same time. The spring tension on the striker guide also serves as a buffer.

Edit. Those heavy inside marks could have got there on 3 70% oveload shot tests for all I know.

Interesting. I re-checked my collection after your post. All three military pistols show evidence of the striker guide hitting the frame, my four commercial .30 Luger examples show no such evidence.
