Thinking about chopping my P-07 Duty

[DP509]

You could purchase the CZ P10M?

Keep it covered, nobody knows what's underneath your shirt.

AMEN - please don't chop it a ruin a great gun.

I wouldn't do this to a CZ, but I understand your desire to do it. I do a lot of projects just to see if I can pull it off. It's the need to produce something with your own labor and ingenuity, so I love this thread. I don't have to want to do the same project to appreciate your project and how well it turned out. Congrats and I'm sure you'll get the minor kinks worked out with the slide failure to lock back. Here's to home projects!

Excellent work! That looks just about good enough to be factory. I would totally buy a P07 like that

On the springs, personally I would try to modify the hammer spring rather than the recoil spring. The stock P07 recoil spring is great for all around use, and so far you have only modified the hammer spring. By changing the recoil spring you will have a second variable to balance.

Hammer springs are very cheap and if it were me i would buy a couple different weights and experiment by cutting them until they work just right. Sounds like you don't have too far to go right now to get there.

By the way, how did this change the DA pull?

Thanks, everyone, for the comments. While I'm not the OP, I still like reading the ongoing discussion.

And for those who suggest not to, I want to bring you my perspective. The first handgun I had ever bought was a 1911. I would like to continue running that if it weren't so expensive to shoot. It may make some of you nauseous, but I'd rock a gov length slide on an officer's height frame if I could. I like the standard length slide on a shorter frame. It may not look super pretty, but it would be the most effective set-up for me. That said, the CZ P-07/P-09 is shooting 9mm, cheaper than 45, and I need that change. Also, I still like the 1911 SAO w/ manual safety and the simplicity of the design. And like a 1911, the omega system doesn't take an armorer to work on. So, considering everything, of all the firearms to chop, why not a P-07/P-09? I don't want to move to a striker-fired action handgun. No interest. I'm also not interested in any micro pistols either. I've looked at the new S&W CSX. But if I use a P-10S mag on a P-07, the height of my P-07 is now nearly the same as a S&W CSX. You could say my chopped P-07 is a P-07S aiming for that subcompact size. So why would I get a super short barrel with the same amount of height? I just don't want my grip hanging out during the summer months. So truly, after making the chop, the grip is perfect for my application. Lastly, I can have a 19-round (P-09/P-10F) mag as a backup, so I'm loaded. Again, I don't see any downside to performing this chop as it serves my needs.

It does indeed have to be done correctly for it to work out. But as long as all measurements are triple verified before making cuts/drills, it's fine. On another note, if they sold a P-07S (P-05?), I'd have already bought one.

Again, I respect everyone's opinion. I'm just giving you mine.

I must say I do enjoy tinkering with firearms. So, I guess that's a part of it too. I was very concerned about destroying the P-07, so I put the idea on ice for so long. And as you may have noticed in the discussion, I looked at the engineering between a CZ-75 and RAMI to find out what was different and what wasn't. But the more I discovered that a good number of the RAMI fire control group parts were interchangeable with CZ-75s, I believed this was doable. Thanks for the comment!

Also, inthevalley:

Thanks for the compliment. I ended up getting an 18-pound recoil spring from CGW. I did the hammer spring math and am confident with where it's at. I don't want to mess with the hammer spring anymore because I don't want any light primer strikes. And I want to mention again that this hammer spring is longer than a RAMI hammer spring. If the same hammer springs are used between the CZ-75s, P-07/P-09s, and RAMIs (which are the same but just cut), I know I'm not truly messing with any of the engineering. And after the updated recoil spring, the cartridges land 6 feet away without any lock-back issues. I'm thoroughly enjoying this pistol.
As for the DA pull... I cannot comment. I primarily use the manual safety, so I haven't noticed a difference. I did some very light polishing on the hammer strut so DA it would feel smoother. Therefore, I can't tell the difference when considering just the chop alone. All I have to say is I like it, and it hasn't seemed to have changed too much.

Please post if anyone else has any suggestions, opinions, or ideas!

I really enjoy competing ideas.

Thanks again!
