I put the Boss Components G10 Palm Swell Grips in stealth black on my CZ Shadow 2 OR competition gun (with no magwell), and they are spectacular. The aggressive G10 knurling locks the gun into my grip perfectly and performs flawlessly even with sweaty hands, providing zero slippage during rapid strings of fire. The ergonomic palm swell fills the hand beautifully, giving me the rock-solid stability and control needed for Pistol New Zealand Action Pistol and CMP Bianchi Cup matches. Plus, the stealth black look gives the pistol a clean, professional aesthetic. It is an exceptional, match-grade upgrade!
I mounted these Boss Components G10 Palm Swell Grips using the factory CZ Torx grip screws, and the fitment is absolute perfection. The screw holes are precision-machined to the exact depth, allowing the stock Torx screws to seat completely flush without binding or protruding into the magazine well. Even after grueling, high-round-count strings of fire, the grips stay securely anchored with zero shifting, backing out, or loosening.
If you are running a CZ Shadow 2 OR with custom low-power-factor reloads, the 10lb Boss Components Progressive Spring is a game-changer. I swapped this into my optics-ready setup to tune it specifically for my tailored hand loads, and the performance is incredible. It tracks beautifully, eliminates slide dip, and ensures 100% cycling reliability even with lower-pressure rounds. The progressive rate does a fantastic job of absorbing the recoil while keeping the dot steady in the glass. It is an absolute must-have for anyone looking to optimize their Shadow 2 competition rig!
I installed the Boss Components Progressive Spring into my CZ Shadow 2 Optics Ready (OR), and it has been absolutely stellar. After extensive use, it has run smoothly without a single incident, hitch, or malfunction. The progressive tension is a perfect match for the Shadow 2's slide weight, delivering a noticeably smoother recoil impulse and keeping the red dot tracking flat for incredibly fast follow-up shots. It feels robust, well-engineered, and handles factory ammunition perfectly. If you want reliable, match-grade performance for your Shadow 2, this is a flawless upgrade.
Adding this recoil spring has greatly improved. How flat my gun shoots now
It has made a significant difference. And i'm so very happy that I added this into my pistol
Just recently added an extended mag release to a new CZ TS2 green. Let me tell you, without it there’s no way I could release the mag without twisting my hand around and shooting spectators 😝. The extended release fits straight on, very good quality and does what it says.
I shoot a custom CZ and was looking for a polymer grip with a palm swell profile. The grip fits my hands perfectly, and I have full control! The only issue was that the grip panels didn't match my magwell, causing the rear corners to dig into my hand. My Dremel helped out there. Now everything is perfect.
I am so happy that I got the tungsten. Guide rod the amount of weight. It adds to the front of the barrel, makes shooting so much flatter and smoother. My CZ shadow 2 doesn't even move when I pull the trigger. Thank you for this
Im using these grips on my CZ TS2.
Customer support already told me that these wont fit a TS2 - which is correct.
I tried them anyways and they do fit if you file a little edge on the bottom so the grips dont poke in your hand.
The price was reasonable, the safety is exactly what I wanted, and the delivery was quick. I will be glad to do business with Boss Components for future purchases.
As always, very quick delivery and great product! Super tight fitting, took a little elbow grease to get them on but that's a good thing. My last lot of OEM base plates would launch themselves off when the magazines hit the ground so this is a great upgrade and adds good weight. Will always comes back to Boss Components for gear, cheers!
