I've got one of the first Gen 17Ls from the 1990s, great factory trigger, looks quite a bit different from the later gens obviously, but I've kept it a long time. I had one of the G34s too, but got rid of it as I bought it to shoot a specific class but decided I was in enough different IDPA/etc classes already when I was shooting that.
My gen 1 17L will shoot pretty comparatively with my Sig P210 off of sandbags, not better, but it'll run right up there close to it in terms of groups and consistency at 25m and out to 50m. Pretty good considering I paid $500 CAD for it in the 1990s sometime. Heh, won't shoot +p out of it though, it likes White Box 115gr just fine, and some 124 and 147 handloads have been pretty decent with it too, oddly enough.
