CZ Tac Sport problem

[rifleman338]

I posted this on the IPSC forum also but thought that I wouyld try here.
I have a CZ Tac Sport in 40cal and the problem that I am having is that when I install the supplied buffer that it comes with, when the gun locks the slide back on an empty mag it seems to want to stove pipe the first round in the fresh mag when installed. It seems that the slide does not get to travel back far enough, but it's locking itself back on the last round. This problem happens when I release the slide with my thumb or rack the slide to release it. Loads are not long in COL as it's the same load that functions great in my G22 (and in this gun without the buffer). I thought that by using the buffer it would add some life to the gun.
Any thoughts ?

Dump the buffer and use the appropriate recoil spring (proper weight - 11lb if I remember correctly)

is the buffer installed properly? I would continue to use the buffer, but maybe you need to shave it down a touch.

Thanks Slavex, yes the buffer is installed properly, I made sure of that two or three times. I was thinking of shaving it down but was not sure if I was supposed to or not. I will give that a try and see what happens.

Is there a lot of play/wobble in the mag when it is seated?

 

[rifleman338]

The mags seem to fit and function fine. All is well without the buffer installed, but once it goes in, everything goes to hell.

Try removing the buffer and see if it persists.
