Welcome to the forum, you can get the lighter hammer spings at Wolf springs.

Welcome, unfortunately even with the 18 lb. spring it's going to be stiff. It's just the way these weapons are. Having been a revolver man during my 20 plus years in law enforcement, I'm used to cocking the weapon as I draw it from the holster so the stiff DA trigger pull is not an issue for me. You have found a well designed, rugged, and reliable firearm but there’s only so much you can do. Every weapon has idiosyncrasys and the stiff trigger is one of those. Just take the time to learn the weapon and it will serve you well. Again, welcome to the forum.

I will have to say from personal experience....the 18 pound spring from Wolf makes it very manageable. Welcome to the forum!

Also if you go for the lighter hammer spring you will end up with a "hair" trigeer for single action.

One way to counter this would be to get a stiffer trigger spring (not sure if anyone has tried this).

+1 for the 18 lb hammer spring from Wolff. The single action does become light and requires a little technique to manage after the DA pull. With a little bit of practice and it's not only manageable but excellent.

Why change the main spring? Is power of the 9mm Mak about the same as a .38 special

Not sure why you are asking this. You asked for ways to lighten the DA trigger pull. They gave you the answer. Replacing the Hammer spring directly effects the trigger weight. It has nothing to do with the power of the round.

Yes.

Also, a worn recoil spring won't bleed off enough energy and the heavier recoil can, over time, batter your firearm and cause quicker wear and breakage.

I have heard an interesting theory which suggests that a heavier recoil spring on simple blowback handguns actually causes heavier recoil. The theory suggests that a heavier recoil spring keeps the chamber closed longer which allows for greater pressure buildup in the barrel which leads to heavier recoil (and possibly higher muzzle velocity). I have no idea if it's true or not but it's certainly an interesting idea.

OK that makes more sense about your question now. We had been discussing the hammer spring. But there are two "main springs"; hammer and recoil, so it was misleading what you where asking.

Allot of people don't like the felt recoil of the P-64, because it's built on a small frame you can't get around it much. A stronger recoil spring helps. You can't go to strong as it will prevent the slide from cycling fully. The standard is an 18 pound recoil spring. I really like the 22 pound recoil spring on my P-64, it works really well. The heavier spring does reduce the felt recoil. I can feel the difference between the one with the 22 lb recoil spring and my other two with standard springs.

Also with the short length of the recoil on a blow back gun, over time the recoil spring will wear out. In most cases the shooter will feel real bad recoil but it can cause damage to the slide and frame.

The recoil spring is not hard to change. Just keep in mind that some of the Older Wolff springs will need some fitting. See this: viewtopic.php?f=3&t=3447&p=39176#p39176

Also for replacing the included firing pin spring refer to the manuals and watch juniustaylor's videos:
