The only thing I could see on their website is that break-in rounds should be "Full power", but not +P 230gr.
From the Wilson website:
Quality ammunition is important when shooting a 1911-style pistol. We suggest quality, domestic brass cased factory new ammunition for best results. It is important to use ammunition that closely approximates the profile of 230 FMJ ammunition for best reliability.
Your Wilson Combat pistol is a precision-fitted firearm and deserves high quality ammunition. The 1911 handgun design requires ammunition to fall between a range of parameters for proper function.
For factory ammunition, only our line of custom ammunition is specifically designed for 1911 handguns and it will be the optimum ammunition for your pistol.
http://shopwilsoncombat.com/Wilson-Combat-Custom-Handgun-Ammunition/departments/134/We do not recommend +P, 230 grain ammunition in any compact 1911 handguns.
We do not recommend Critical Defense/Duty ammunition or other ammunition with a soft polymer tip.
Your new pistol is tightly fitted to very close tolerances to achieve maximum accuracy.
Even though a Wilson Combat pistol has been thoroughly tested by a professional test shooter with almost 100 rounds of our custom loaded ammunition, it will still require a thorough break-in to achieve reliable function across a broad spectrum of shooters and ammunition.
Load and unload your new magazines several times and keep them loaded for several days in advance of your first range day to allow the stiff springs to take an initial set. This will make them easier to load and reduce pressure on the bottom of the slide that could cause a malfunction.
Ensure that your pistol is well lubricated with a light oil like Ultima Lube II Oil or Ultima Lube II Lite Oil during break in.
http://shopwilsoncombat.com/Ultima-Lube-II/products/432/Shoot a minimum of 300- 500 rounds of full charge ammunition through your pistol prior to disassembly and cleaning for the first time. Keep your custom pistol well lubricated throughout this break-in period. If you experience recurrent malfunctions, clean and lubricate your pistol during break in regardless of round count. Firearms will require fresh lubrication when new since most guns leave the shop with minimal lubricant added.
