I shot IPSC Standard Division, so I know that I will have to remove the Thumb Rest and change my Barrel, that have a Tungsten weight.
But I couldn’t find anything about the slide racker.
APPENDIX D2 — Limited Division
21 Authorized Modifications
•Internal modifications to improve accuracy, reliability and function (such as spherical bushings, Acc-U-Rails).
•Replacement barrels – provided they are the same length as original factory standard.
•Exchange of minor components (springs, safeties, slide stops, guide rods).
22 Prohibited Modifications
External modifications or features such as weights or devices to control or reduce recoil (such as but not limited to thumb rests or components which could be used as such).
Thanks.
