Played around with the new HK P30SK in LEM today.

For what it's worth Constantine.... the DA pull on your new 45 CT is actually pretty good. It's well broken in from lots of dry fires. It was the guts form my full size HK 45 but I sold my full size as an LEM, so I put the smoother guts into that one for you so it's moar better.

The 45C hammer spring is shorter than the full size springs... I tried putting a 10lb spring in and it actually made it stiffer because it's compressed way more. Leave that spring alone...

and it already has the light FPBS in it. You don't need to change anything. Shoot it. :p
 
ROFLMFAO!! Oooooooh!!! Wow. That's hilarious and awesome. The texting with me being an idiot and the fact that it's already good to go.

Thanks! I'm looking forward to picking it up tomorrow as you should be about picking up that, other, thing.. I sent. Lol. Good ol' trading. ;)
 
Why the firing pin spring from Wolff instead of HKparts?

I think you meant hammer spring as that's what I said. As for why, because they're a lot cheaper from Wolff and they do the same thing. In owning both I didn't see any difference in quality and I actually got resulting trigger weights that I liked better with Wolff.
 
My 2 cents. Why all the spring changes to a tactical arm? I would think and trust a maker as HK knows their product. My High Standard Victor's, 22LR, are range toys having a trigger that can be adjusted scarey lite. I endeavor to keep springs stock.

Because there's no reason to deal with a 12 lb. DA if you don't have to. HK uses overly heavy mainsprings, when lighter mainsprings will still allow 100% ignition with an easier pull. We're talking about lightening springs so that they're still close to twice the pull of a stock Glock in DA.
 
And Glock's, at times, are known to have light primer strikes. I don't think the term "light strike" was hardly known before Glock came about. :)
 
I've never had light primer strikes with a Glock, but for that matter a striker fired pistol and a hammer fired pistol don't have a ton in common. The Glock's lighter trigger pull is not a result of too light of a striker spring compared to the hammer spring on a DA/SA pistol. The cycling of the slide is being used to precock that spring on the Glock whereas on a DA/SA pistol that isn't happening. As a trade off you don't get "second-striker" capability with most strikers (Walther P99 and Canik TP9 variations excluded). I reference Glock because when people hear about lightening pistol triggers they reasonably worry about liability, and my point is that "lightening" in this case still results in a first trigger pull heavier than a huge segment of the pistol market (that being striker fired pistols).

If you don't want to replace the mainspring that's certainly a choice you can make. HK's DA trigger pulls from factory are ~ 2 lb. heavier than most DA trigger pulls. With a mainspring swap that take a matter of seconds you can have that down to 1-1.5 lb. below what is relatively the standard of 10 lb. Obviously you have to test the pistol to make sure you don't get light strikes with the lighter mainspring (though you also have to test it to make sure it's good from factory too) but unless going very light the vast majority of people here and on HKPro have not had problems (another reason I like going with Wolff is you can get a 12 lb. or 10 lb. hammer spring and the former brings you down to the 9 lb. DA pull territory and in literally thousands of rounds with such a setup I never had light strikes). The springs are sub $10 so even if they don't work for you it's not a big investment lost.

The mainspring effects both DA and SA trigger pulls. IMO the lighter and shorter the pull the less gripping force will be. That's not productive for a poly frame pistol. Pistols with light/short triggers tend to be full size and all steel.

This honestly makes little to no sense to me. When I swapped out the mainspring I did not grip the frame any tighter or looser than I did before, nor do I see why you would. You would still need to control the pistol and a firm grip is required either way. I'd also point out you're going from 12 lb. DA to say a bit over 9 lb. DA and 5.5 - 6 lb. SA to a little under 5 lb. SA (the hammer spring has less impact on the cocked SA pull). It's really not as dramatic as you seem to be intimating. Actually in thinking I could almost argue the reverse. An overly stiff trigger will see a lot of the hand strength going into pulling the trigger and could distract the shooter from having a proper grip.

Both the Walther PPQ and HK VP9 are examples that counter the need for an all steel frame or heavier weight for reliability with light triggers, not to mention the countless modified striker pistols with even lighter triggers. That said the HK P series is ludicrously resistant to limp wristing. Try as hard as I could and I honestly couldn't get it to limpwrist nor could my wife who will limpwrist a Glock every time, but the polymer HK uses seems a bit more rigid than some of the competition and the grip is actually quite thin allowing her to get a good grip even with her tiny hands. The CZ P-07/P-09 (with the option for cocked and locked carry) also have decent triggers in SA and I have never heard of that encouraging folks to limpwrist.

Off-hand I think PPQ and VP9 have at least a 1/4" travel with a weight of 5 pounds. I've handled an original P99, SA pull I would call mushy compared to my 745's (non 1911), crisp. The pricier 1911's are said to be about 3.5 to 3.75 pounds.

The pull weight of those pistols is still less than even the SA of the HKs after a spring swap and the length of travel is dramatically less than the modifications being described here and people can shoot them without inducing malfunctions so again I don't see a reason for concern. A typical 1911 is in the 5 lb. range. As for the likes of the higher end guns, yes but now you're comparing custom guns as expensive as $5000 to production guns costing $650 (nowhere did I suggest or say that the SA would go as low 3.5 lb after a spring swap so I'm not sure the need for comparison there). None of this changes the fact that people can still shoot polymer pistols with light triggers just fine, especially when we consider the aftermarket companies like APEX and etc that can get the pull weights even lower if desired and closer to the high end 1911s (again nothing I suggested or others suggested doing here would get the pull weights that low anyway).

I have owned S&W third gen pistols that have great triggers (better than HK) and the 745 is in a different class from that being designed specifically for target shooting. It's going to be hard for any current production pistol to compare to that. It's not in the same league as the pistols being described here when it comes to trigger (like NFL vs. high school JV).
