I shoot a 19 with the Truglow night sights in question. It's also a carry gun.
However, if you look at the Nationals - you don't see that many 19s - mostly 34s. I don't think they are realistic carry guns (but some do rarely). Ducking for cover here.
An SSP gun that gets extremely tricked out is defeating the purpose, oh - it's a game but not as gamey as IPSC. Still ducking.
