What's the essence of CGW upgrades?

[SI VIS PACEM PARRABELLUM]

Can't imagine CZ handguns are great, except that they need upgrades right from the factory.

Thing is it's a matter of wanting upgrades not needing them and many of us like upgrades. Maybe look around and see how many different aftermarket parts are available for the multitude of firearms out there. Really it's an easy concept to understand.

There is need and want, 2 different things. I felt my PCR was good right out of the box, sent it to CGW and it went from good to great.
Did it Need it NO, Did I want it YES.

My guns are for self defense purposes, instead of for competition. As a result, my rule of thumb is to only upgrade a gun with genuine parts from the manufacturer, unless the upgrade is exceptional. In the CGW case, my worry is that the weaker spring will degrade with time and fail to fire the primer in the future.

I use the 15lb hammer spring in all my CZ's. They ALL have north of 10,000 rounds fired and the one I carry the most has north of 30,000 rounds fired at this point. I fully trust them to fire when needed. Springs of any type can be considered wear items and if you're concerned about them weakening they can be replaced at regular intervals. OEM factory parts wear just the same as aftermarket parts and you should know that like everything else manufactured today gun companies procure things like springs from secondary sources.

I'm not talking about the materials of these parts.

Imagine it takes 10 inch lb to ignite a primer, and the company spring is capable of delivering a 20 in lb blow, well above the threshold, but an aftermarket one is only capable of 12 inch lb. Both will ignite the primer, but there is only one solid one you can dependent on.

 There are primer brands known to be very soft such as Federal and brands known to be pretty hard such as CCI. The idea as with all other aspects is to tune the hammer spring in that you find the lb rating that fires everything reliably. Just because a spring is rated lighter does in no way mean it is or will become unreliable. You find what works with your combination.
15lb hammer springs work perfectly in my CZ's and I've not had any issue with them.

Cajun gunworks takes an already great pistol and makes it better.
Smoother ,shorter reset , lighter trigger. It’s all about what you are wanting from your pistol. To start with ..the biggest improvement you can get is. LOK grips palm swell bogies .

Bought a P09C. Double action equated to 11lbs approximately.  Single action ok. Debated what would be the way to go. Ended up I just ordered the Pro Pack. Measured the factory roller prior to ordering it was .215. Email support was told to order .220.......it was closest.
Long story short.....installed everything (roller .220) but the optional sear springs left factory in. Let me say I polished nothing. I did relieve the trigger bar spring some. Double action 6lb 10.7oz over 5 pulls.........single action 2.6lbs. Short reset and reach is much better. I might return to stock trigger return spring.

Using this thinking we can see that...

Upgrades are available for every gun sold today. Therefore, there must be no 'great' guns.

Your right. As the factory puts them together they serviceable duty pistols. I like P07/09/09c/09f as an overall battery of arms. Hammer fired, decocker, polymer, and capacity. I just felt the double action was a little stiff (11+ lbs) out of the box. I made the trigger pull shorter along with the reset.

Litigation creates some of the items we are discussing. I didn't want to wait 1000 rounds for the pistol to "break" in. So for less than the price of a cheap 2011 I have a pistol that can be abused on a daily.

CGW provides 4 key sevices that differentiate them from competition :  Parts and technical how to information for DIY'ers, on line technical counsel, upgrading sevices and new upgraded pistols.   Their services are of particuliar value to new CZ owners who buy the lower end  Omega triggered CZ models which really need a sow's ear to silk purse trigger action performance make over.   

My personal experience was with a used CZ P07 which had a heavy DA trigger , A soft spongy SA trigger, and a tough to rack slide.  Looked good in the gun shop but was a dog actual performancewise.  Took a lot of personal counsel, the written how to's, upgrade parts, and persistence to get it's performance close to a good Sig DA/SA pistol. 

The cons, from my perspective, on having a CZ is common parts availability shotages.

My last 2 pistols sent to them had the pro package installed and the barrels cRn coated. The ramps were coated and would not feed at all. I returned them and they polished the ramps to remove the coating which corrected the problem.
How can you send a firearm in for upgrades to have the best possible self-defense weapon and they don't even test fire it. To me that was unacceptable.  And don't let them tell you they can DLC an aluminum frame. I know first-hand that they can't. With that said the trigger was nice even though the front sight which CGW replaced fell off my sp-01 after about 20 rounds.

I don’t know where you got that.  CGW’s site has said for a long time they can’t.  From their page

    What can DLC be applied to?
Although some places do offer DLC for aluminum, we only coat steel or stainless-steel parts.  DLC is suitable for frame, slide, barrel, controls, and internals.

I'd like too see some pics and proof of these claims. I find it interesting that you claim a front sight "falling" off when those sights are pinned in place. The pin not only holds the sight but also retains the barrel bushing.

I would too. Pics or it didn't happen.
