However, doing some reading up on the gun has me hesitant. The hollowpoint ammo issue has been in play for years now, is that still the case for new guns?
you have to realize that some guns were made to eat certain ammo shape/style/weights. when you take a platform and modify it to eat something else, you may not end up with the best solution. the 1911 was designed to eat FMJ/BALL. now most of not all mfg of 1911 try to make them eat JHPs and such, but the ammo industry changes faster then the gun industry. the Sig P220 was afaik the ONLY gun designed to eat 45acp JHP from the ground up. im not sure about the CZ.
If you want a CZ97, then YOU will have to do some testing with varous ammo to determine what it likes to eat. there isnt alot of short cuts especially if its going to be your HD/SD gun.
there were/are? some issues with the mag catch? on the 97 that caused the mag to sit lower, thus having feeding issues. im not sure if CZ has fixed the mag catch issue or if its a combo of mag and mag catch. the EAA 45 mags will work in the CZ97, but have a gap at the base.
If so, can someone give me an overview of what needs to be done to the 97's to get them functioning reliably with the JHPs that I'd like to load up for self defense purposes?
you should rethink or inquire as to what ammo you want to use for carry in the woods. Humans are soft skiined animals, whereas others are not. You want more penetration in your ammo then just HPs. although HPs may do the job, i would want something with more penetration.
1. Polish the feed ramp. Seems simple enough in theory - some hollowpoint bullets are too wide or the existing feed ramp from the magazine? What does polishing do? Make the surface slicker so the ammo feeds? Not sure I understand the nuances there.
polishing makes it easier for the nose of the bullet to slide up the ramp and into the chamber. sometimes there are lips/burrs or changes in profile that may cause feeding issues. a good gun smith will be albe to recoginize and fix that.
2. Change magazines. I seem to remember reading something to that effect somewhere - that the EAA Witness 45 mags work with the 97 and work better?
yes EAA mags do fit/work.. but depending on whats wrong, it may not make a dif.
3. Replace the recoil spring with a Wolff. Dumb question here, but how does a soft recoil spring negatively affect the pistol? Feed issues?
Depending on what type of ammo you plan on using. If you want to shoot alot of hot ammo, then maybe a heavier spring will help. everthing in a gun works togeather and is tuned to work with certain ammo weights/velocity. if you change one,it maynot like the other end. If you install a lighter (softer) spring, and you shoot hoter ammo, you may endup causing more wear/tear to the gun.
4. Replace guide rod: Swap out the plastic one with a steel one. Same part as the CZ 75's?
if you dont like the plastic one change it. its your $$$.
some general comments.
since youre a noob. you can worry and fret able all sorts of things and spend $$$ on changes to the gun. You havent even shot one, so do you really know whats going to happen? Not really. so why not just buy it and go shoot it before you decide on any change. if/when you come across any issues then deal with them. its all "what ifs" at this point. you can do "what if" until youre dead w/no gun in your hands too.
spend more time shooting and trying, then see what changes if any are needed.
there are alot of people that are traditionalsts. they dont like or belive in change. IE plastic in guns is a sin and should be shot or put to death. Or MIM parts are bad and dont hold up. It all depends on the sit. there was a time when plastic on cars was considered "cheap" but look at your car now.
also, there is alot of mis information on the www. just because its in print doesnt mean is true. even what i have typed here can be wrong. If you want to play with guns, find a good trustworthy gun smith and go pick his brains. chances are, he will see alot of gun returns or broke ones and you can get an idea on whats what. But dont forget that anyone can make a lemon. sometimes the person that gets one of those lemons can squeel so loud that you woudlnt want to have one next to you. but that doesnt mean ALL of them are lemons.
if you want idiot proof, rethink or go buy a Glock. many people think they are "perfect" or "idiot proof". when i see stuff like that i think of Murphys laws. Put/spend more time & $$ into education/training youself. The gun is just a tool. if you suck, dont expect the gun to make up the difference.
unless you know whats wrong, you can spend alot of $$ trying to figure it out. you can take the shotgun approach and change many things, but in the end you may not know what the root cause was. swappiing parts could be done, but again, if you dont know whats wrong, you are just chasing shadows. also, being a noob, its better to have someone know whats going on do the repair/mods. at least then if they screw it up, you may have some recouse. if you do it, its your fault and you eat it.
