Bill, I think we should put rock on
"double secret probation" if you remember that from animal house
if you measure from the top of the rail to the bottom of an "average" feed ramp a 9mm 38 stupid 40 10mm... will be around .250 ish, I do not know for sure the corrosponding angle but it is around 31 deg.
the 45 ramp is .375 ish and works better on agressive hollowpoints at .420. Sometimes a non ramped barrel in 9mm catagory will overhang the ramp cut on a 45 frame.
If you took a super ramp frame and shot .45 ball ammo and espically with 7 roung mags you would probably be a happy camper. With a large nose hollow point with 8 rd. you may very well get nose dives.
Brownells needs to make 750. profit per colum inch in the 175+ thousand catalogs they send out. If they do not profit that amount, they drop the part like a bad habbit. We still make the ramp and unfortunatly our web sight does not reflect all the 175 ish parts we make. I am not sure but Ned or Chuck may offer one for sale also?
