MCARBO CZ 75b trigger spring kit review.

[Underwhere]

The CGW floating trigger pin alone is $13 plus shipping.  Personally, I'm very happy how the MCARBO kit transformed my two 75's, it was an incredible change for my two handguns. I never thought that was possible for under $100+.  Correct me if I'm wrong, but does CGW or CZC even sell a lighter sear spring?

Oh, as of yesterday, there was 9 reviews at the MCARBO site for the CZ75 kit.

I haven checked the cost of the floating trigger pin. I will still always buy one. I don't know how you would detail strip your gun and re-assemble it without one.

Lighter sear springs can cause issues with the hammer. CGW explained it to me a while ago. I forget what they called it. I believe something like "hammer bounce" or "sear bounce" or something like that. That in some cases lightened sear springs can cause the hammer to fall to half cock while shooting.

I have Cajuns lightened sear springs as part of their kit for the P07 and P09. So yes they make them. They gave me guidance on when to use them and what to expect for reliability.

If I recall correctly (I don't have the best memory), they opted not to produce a lightened sear spring for the 75's.

For just pull weight I would change out the hammer spring to a 13 pound spring.
I would also change out the firing pin block spring and firing pin spring.

If you get a lightened trigger spring all of this would significantly drop your pull weights to what the MCARBO kit is doing.

That's probably about $20 worth of parts.

However I personally wouldn't recommend just that.
I would always put in a hardened firing pin retaining pin as well as a floating trigger pin.

After doing all of this you'd have a reliable and lower pull-weight CZ.

To get a much crisper break and better reset you will want a hammer, a sear and a disconnector. To many this is unnecessary and they are fine just lowering the weight with springs.

lol, it's not like I'm spending $10 for a $5 pin. Plus who knows what else is in that shipment?

The question for some of us is this:
Why skimp on the springs with an unproven kit just to save a few bucks when you still have to buy the rest of the parts from CGW?

Probably the same reason I have multiple grips for my CZs and 1911s, and different springs from Wolff and Wilson. I didn't realize cost was such an issue, I don't always buy one spring from one manufacturer. Hell, I have a drawer full of 1911 recoil springs, some duplicate weights. For the record the Mcarbo is going into a 75bd, my PCR gets CGW guts, but CZC Grips and sights...but now that I've said that I'm certain there is going to be a question on "why mix and match?" again (because I got the grips, gold trijicon dot, and black rear which I like more than the CZW offerings). And another mix and match I might do is put the PCR slide on the 75BD frame. Now I will say I'm in CA, therefore my option on CZ guns is crippled, so pretty much anything that comes out gets a try.

I could see the hammer bounce happening, and makes sense. I'll omit the sear spring plus didn't want to go in there till I get the new lifter. Question, can I remove the trigger bar without removing the sear cage? or can I lift the sear cage out completely in one piece like with the 75 B models?

Thanks for the sear spring tip, makes sense.

It was a common sense question, sorry to bother you with it. Curious about your logic for purchasing from both sources, that's all.

It's all good brother, rereading what I wrote, I sound saltier than I meant it. I would say being in CA is the broad answer to your question.

This potential hammer bounce thing using a lighter sear spring has my attention.  I have 400rds through each of my 75's with zero problems (800 total), and no light primer strikes.  That's a pretty good sampling so far, and if this hammer bounce should occur, about how many more rounds will it take?  I'm learning, I have no idea so bear with me. Is this one of those things where it might happen or never happen to some?

You can if you are running only SA (no disconnector) and you remove the trigger pin. Otherwise you gotta take the sear out.

[Underwhere]

I believe it is a problem that happens at speed.

But CGW knows more than I do. I'm merely repeating what they've researched and told me... And likely omitting many facts in the process. I don't have personal experience with it.

You would already notice it. It happens with 1911s with weak springs and isn't something that actually "gets worse" it happens from the get go. Imagine putting weak springs on a car and going over a bump, the car bounces a few times before settling, same with the hammer.

Thanks, then both of mine should be ok based on that explanation since neither of mine have not dropped to a 1/2 cock position.  I shoot at an indoor range where no more than two rounds of fast firing is allowed.

Decocker sear cage can be removed intact if you use a slave pin.

I received my third MCARBO CZ75b kit, but I decided not to install it in my Tristar C-100 since it already has a good trigger for a CCW.  I didn't want to waste the kit, so I have another new CZ75b polished stainless on the way... .

I have heard of someone buy a gun because they had extra ammo or too many mags, but never because they had a few extra springs laying around....but, it makes perfect sense to me.
