I see and acknowledge the issue... but wouldn't it be easier/ quicker/ less expensive to simply learn to load for the barrel as it is ? Our testing in the Ammo & Handloading forum shows that shorter cartridges often have more accurate shot placement.
Reaming always seems like a lot of time and trouble, accompanied by a LOT of unknown risk factors.
If I reloaded I'd absolutely just adjust my ammo but my rounds OAL are already 1.110". They'd have to be around 1.030" which is quite short and I don't have the motivation to handload. As it turns out the barrel is DLC not nitride so it wasn't too difficult with my HSS throating reamer. Lots of cutting lube, one turn, clean, plunk test, and repeat. Needed about 8 turns for the bullet to barely drag on the rifling.
Played with it over the weekend shooting 25y B8 drills. Tried a 19# mainspring and replaced the sear spring. The factory sear spring’s sear leg was slightly short and tricky to position correctly. Tried a WC 13# flatwire recoil spring but really preferred an ISMI Glock 17 11# spring. Despite the lower rating, the Glock spring was returning the front sight level while the WC was returning slightly high with 130PF 147gr. Probably due to longer free length and increased preload. Picked up a 1911 flat bottom FP stop to play with in the shop. The firing pin hole is drilled lower in the DWX but I can throw it in the mill at work to make it match. I took some measurements and the slide will fit a standard 1911 round wire recoil spring. I’m going to open up the recoil spring hole and modify an X5 Legion guide rod to fit. Opens up spring tuning to the full suite of 1911 springs and adds a little more weight under the muzzle.
The factory mag release felt a bit stiff even after a bit of buffing. Picked up a Wolff reduced power 1911 spring pack. The #3 felt just right.
Also, LOK palm swell Veloce grips for the Shadow2 feel just as good on the DWX as my SP-01.
Once I get the guide rod and fp stop situated, it’s off for optic milling and refinish. I'm loving this thing. Keeping my eyes peeled for a DWX Compact.
