Non-expert question out of left field here. The front spring lug not breaking away from the rest of the slide is basically what keeps the back of the slide from recoiling all the way back off the slide rails and hitting you in the face. How does one know how much metal you can remove from a slide, before you've gotten into the safety margin of the part?

Similar to the above question, how do you know how much to remove in general?
Is it art based on experience, or formula, or a combination?
Then is pattern you choose to remove material art or a certain pattern?
Very cool.

Best I can address the two questions above is by personal experience. I can not give a technical answer to your question.

When I first started I was pretty worried about slides cracking but over time I have not seen any issues. Plus many aftermarket slides you buy are cut way more then this one/
I have seen some issues with open guns used for USPSA and the like. But they get alot of abuse.

I don't believe that the action of the slide against the frame is as severe as it seems.

Have either of you grasped a slide and frame together with your hand and fired a shot to induce a malfunction? I have and it is not as violent as you would think....at least 9mm that is.
I have a personal line that I will not cross as far as how much metal I would remove , but the slide in the pic above does not come close to that.

I don't know if that helps but best I can offer at this time

Yep, great answer, thanks. I read “art. with experience”.

Your work looks good. It looks as much an art as it is science.

Midnight Bronze and Graphite Black 2 tone

Front cut looks funny in camera but that is not the case in person

Thanks for taking the time to photograph your work. Always interesting to see what you are doing.

My new CZ PCR and shout out to AllenM

Haven’t been on in awhile but my last post were about an issue with a new RAMI I had bought and it’s issues with FTF. Well decided to part ways and picked up a new PCR. As soon as I received it, I stripped it down and took it to Allen For some slide work and cerakote. I found Allen on this site...

Not to be difficult, but does this machining have a practical purpose?
