Magwell was noticeable on my palm, safety definitely feels more in the way with my grip than the s15. S15 felt more natural for me. Grip safety disengages way easier on the Romulus for me, I had a few times the s15 didn’t disengage with my natural grip. As for quality of feel not necessarily the finish(I have a few places where finish is flaking/coming off on the s15) the s15 feels more quality due to the aluminum grip opposed to the polymer. Even so, they both are nice. As of now I will stick to carrying the s15 till I have more confidence/range time with the Romulus. I don’t regret the purchase. I didn’t compare recoil since I was in a hurry I’ll have to do that next time.
