The Sig P938 has had a history of issues as well, hopefully they are all solved now but "subcompact" and "1911" don't mix real well, a lot to ask from a machine that small. Definitely take whatever slide-gun you get to the range and try a lot of rounds first, and use the grain the most people say works with the particular gun. There are plenty of YouTube videos on every gun on the market where a gun person runs boxes of varying ammo through the gun and gives honest info on what works. The spring rates for small 1911s are critical, not a lot of leeway in bullet weight.
