Went to the range yesterday with the wife.
She shoots a Sig P238 She shot 150 rounds NO Failures, Pistol ran fine.
Solo shot 27 Federal HST 124 JHP No Failures.
Solo shot 50 American Eagle 147 gr FMJ Flat Point, No Failures
Solo shot 21 Agulia 124 FMJ, 2 FTE/FTF
P938 shot 22 Aqualia 124 FMJ, No Failures
There is no comparison between the feel of the Solo and the P938.
The Solo trigger is much smoother. The trigger surface on my P938 needs to be changed to something not as sharp and trigger pull needs work.
Without a doubt, carrying the right ammo in the Solo is the best combination between the P938 and the Solo for EDC in my opinion. YMMV
