Don't change the springs.

The P-64 was designed to have a strong hammer spring, in part, to make up for the fact that it does not have a hammer drop safety.

In other words, you can fire the gun without putting your hand on the trigger. If you pull the hammer back without fully cocking it with the safety off and a round chambered it might fire.

A powerful hammer spring helps to mitigate that.

People have accidentally discharged a round holstering the pistol, with the safety off.

It is more likely to do this if you have changed out the hammer spring. Not to mention you may have light strike issues.

If your trigger finger is too weak to operate this pistol as designed, either train until you can, or look elsewhere.

You can safely carry this with a round chambered, just de-cock, leave it on safe and train with it like this.

This is an accurate, reliable and safe pistol: as designed.

Leave it that way.

:hi: Welcome to the forum.
Good info. Thanks for posting it. Do you feel that the 20# is too light?

Thanks for the input. But I totally disagree with all of what you are saying.

1) When the P-64 was designed, drop safeties were not common so the strong Spring Design had nothing to do with being "Drop Safe".

2) You totally overlooked the historical reason the Spring was designed so stiff. The primary reason was so that it could fire the ammunition made with stiff primer for the PM-63 and other Submachine Guns. This ammunition is now obsolete.

3) Your logic goes against the popular opinion of shooters with decades of experience with the P-64.

ummmmm, one other problem with your logic. The safety, as designed from the beginning, IS a hammer drop safety.
:oops:

Well, you did ask. :evilgrin:

No show this weekend but there's one on the the 18th.

My son just went to the range to try out his buddy's new AR. Going to choke him for not telling me. Could have tested the new P64 setup after cleaning up the extractor and area. I just received a new extractor, plunger & spring, and slide stop lever (ejector)) & spring if it still hiccups.

It just doesn't make sense to me. "Hey guys I'm new here. But I'm going to tell you what not to do with absolute certainty". Kinda how it read to me. Also it's not like these were built yesterday. They were built in the 60s-70s, in any case typically older than I am. So to me it makes much more sense not to look at absolutes but the historic reasoning for something coupled with the decades of experience that we have all shared.

And the weather is drunk here. It keeps stumbling in and out of three different seasons
