New guy on the block. Retired Marine Master Guns who has been around the block a few times.
On polymer frame pistols, I always slap a steel or titanium guide rod in to replace the polymer. Reasoning behind it is to add some weight and let you acquire that bad boy back on target a little quicker.
With the CZ metal platforms, weight is not an issue, but I put the bleep metal ones in my CZs also. No reason other than me being me and just something to play and fumble around with. I am new to the CZ world, I have a PCR and an 85 Combat. I absolutely love them. My PCR has been jazzed up with some Cajun and Angus goodies. It is now my EDC. I already have a battle plan for my next 4 CZ purchases. The finale is going to be a Scorpion
