Heinie Race Cut/ .140 rear sights - still available ?

Does anyone know if Heinie still offers the Race Cut / .140 rear sights for the Glock?

I've E mailed them twice with no reply. I'm only seeing the standard and QWIK .156 rear on their website.

Any thoughts or experiences with the .156 QWIK sights on the Glock for shooting at 25 yards ?

Thanks

Can't help with the race cut but I do have the Straight Eight Qwik on my P30. In regards to 25yd shooting I find them very usable. With my handloads it prints 1 1/2 high at that range, but they are consistant. I did paint the very top seration bright orange to give definition against the black bull. I just shot a 97-3x on the 25yd slow fire B8 target standing 2 handed. I do only have experince withe the stock sights and the Meps on the P30 so take that for what its worth.

Thanks. I have a set of standard straight eight Heinies (1990's vintage) and a set with the .140 rear purchased in 2008. I really like the wider rear notch.

Either is a great improvement over Mepros.
