Wolff vs ISMI Glock

[mysak]

Basically I ended up with a lonewolf frame, 23 slide, and KKM 40-9 bbl. So the question ISMI VS Wolff and spring weight?

[Magsz]

Shrug.

It will depend on your load and what you like.

Between the two, you will get a billion and seven different opinions as to which is better or which feels better.

For the longest time i shot wolf 14lb springs simply because ISMI didnt make a 14 pounder. If i had wanted to lighter i would have gone with an ISMI. There are plenty of debates about round wire versus flat wire so if you want to read about the differences, simply google.

Thanks. I was thinking captured vs uncaptured I mainly shoot 115/124 factory reman or my carry ammo hst 124+p

[mysak]

Stupid question but in my search for answers I found the factory 19 recoil spring to be 18# is there a reason I would run a 14#?

[Magsz]

Tuning the recoil impulse to your grip strength and technique.

This video sums the concept up nicely.

I've used both and I like factory Glock springs.

I have a 19 in the safe with a Wolff guiderod and factory weight spring that has maybe 300 rounds on it and it barely holds itself in battery.

[mysak]

The only reason I bring this up is the gentleman at kkm recommended Wolff 14# I've been running an ismi I don't even know the # for awhile now in my 19 and it seems to work.

[Magsz]

Most people running KKM barrels are probably shooting competitively and 13 to 14lb springs tend to be the norm for most guys running the guns in a gaming setting.

[mysak]

Understood, for some reason the video doesn't seem to want to play. I will primarily be using this for carry if it works properly.

[Magsz]

Stick to 15 or 16 lb springs then.

If you're running standard pressure or +P loads. Stick with the 16lb spring. Stock part, ISMI, Wolff, whatever floats your boat. The lighter the load, lighter spring. Light spring for factory loads or +P ammo and you may run into timing issues as well as beating the crap out of the frame lugs.

Howdy,


If you're running standard pressure or +P loads. Stick with the 16lb spring. Stock part, ISMI, Wolff, whatever floats your boat. The lighter the load, lighter spring. Light spring for factory loads or +P ammo and you may run into timing issues as well as beating the crap out of the frame lugs.

+1!

The 13-14lb spring are for the gamers that are shooting very light loads.

Heavy spring = Heavy loads

Light spring = Light loads

I have a LW 40-9mm barrel for my G23 and a LW captured 15lb RSA and the lights loads that will barely work the slide with the .40cal RSA will chunck the brass 10' with the 15lb spring.

I have a G20 10mm that I'm running a LW captured 20lb RSA that has tamed the recoil and shortened the distance the brass was being ejected by 3-4 feet.

As far as the flat vs round spring goes, to me it doesn't matter as long as it a quality spring.
