Beretta 92 Centurion lightened DA pull

[Munny$hot]

I finally dusted off the Inox Centurion that has been collecting dust since the 90s. The DA is horrid but the SA is sweet. This thing is very smooth cycling and ran like a fine Swiss time piece. Soooo after some research I've found that the 92D spring is the cats meow to cure the stiff DA pull, but getting one shipped to me was @ 13.00 and about a 5 day wait. I did a little more digging and found that by cutting off 3 coils off of the stock spring would bring the DA weight done to 8.4 lbs almost matching the D springs 8.8 lbs. I wanted to insure reliability so I decided to cut off 2 coils instead. I haven't measured it yet, but it sure does feel nice. I'm going to shoot it again tomorrow to compare primer strikes depths. I'll probably order a D spring next time Cabellas, Brownells, etc has free shipping. I basically wrote off non striker fire pistols but this Centurion is starting to grow on me.

do they make extended fire pins for the 92?

I've found that the Wilson Combat 13# spring works surprisingly well too. I think this is about as light as it can get without having to do other modifications to the firing pin block spring, or relying on Federal primers. A couple of hundred rounds of Tula primers, no ignition problems. Of course, Wilson does say that this is rated for "competition only", so take that into consideration.

No, but they do nothing to increase strike energy.

No, but they do nothing to increase strike energy.

But they do help prevent lighter primer strikes when using a lighter hammer spring.

No, that is actually a myth. If it was true, gun makers would just make the FP's a shade longer. Yes I know that places sell "extended firing pins" and make claims about them, but it's baloney.

What reduces light strikes is a striker or FP with reduced mass which increases strike energy for a given spring weight (example: http://lspi.com/). You can also increase strike energy by reducing the mass of the hammer, which is why comp guns have skeletonized hammers (plus they look really cool).

I recall the 92D has a lower mass hammer with the cocking spur removed which would give better hit with the lighter spring.

Some years back when I tuned up Berettas, the stock 92FS hammer spring was 20# and the D spring was around 15# which is about 25% lighter. I did some measurements on the springs and on mine, you could cut 3 coils off the stock spring and end up with a D spring (note: the springs used to have one coil for every 0.1" uncompressed, if they still do then 3 coils is probably still OK).

I think if you go down to 14# or below, you can get misfires but it will depend on ammo primers.

Some people also used 1911 springs, the size is very close to the Ber spring.

That's funny, they make extended firing pins/strikers for CZ's and Glocks and they work just as advertised because the regular length firing pins/strikers are less reliable when using lighter springs...

I have been happy with the D springs
