I shoot Open guns mostly because I like shooting them. To me they feel like driving a 911 turbo vs a Toyota Corrolla. I am now admittedly also old and blind, but wasn't always. I also have a Shadow and love shooting it. It's a great gun, but the Production Division rules are indeed nonsensical. It has really become the defacto Shadow/Tanfoglio Division. With Tanfo now building what is essentially a purpose-built, divisional racing gun, real Production guns can't compete. Maybe we should just call it Shad-Foglio Division and be done with it.
For those who will say it's the indian not the arrow; sure, all things being equal that's true. If you have two guys of identical skill shooting the same stages/matches with the same equipment, they are going to be generally close enough to be swapping places in tiny increments from match to match. Give one of them a much better gun however, and the spread gets much wider.
Scenario: You get into IPSC and on the advice of all the experienced shooters you decide to buy a CZ Shadow and start competing. Over time you get better, maybe even really good, but now you find you are getting your ass handed to you every time you come up against the guy with the heavier gun, the longer sight radius the nice, crisp yet soft out of the box factory custom trigger. So now if you want to go up that next wrung you look at your choices: 1. Clip a couple of coils off a two $2.00 spring and get someone to "polish" the innards or 2. Spend 2 grand on the Tanfo. Pretty easy to guess what most are going to do?
