Are these pretty much no longer made by anyone?

amherst has push pins,like on the early sp1,s. I have an early a2[ slab side -slick side] that came with the push pin. easier to mess with during cleaning and maintenance. just another option!

KNS makes a push-button push pin for the SP1 size hole as well (I have one in mine for ease of use too), but I suspect that the OP is looking to make the rifle as 'original' as possible.

Edited to add the 'push-button' for clarity...

What did the early Colt push pins look like? Ball detents or spring wires like HK? I dont really like the idea of either since the receiver is aluminum and the edge of that hole will wear over time.

A lot of these on GB with prices all over the place
also to your question I think the early push pins were ball detent.
Brownells used to sell one for their repop retro slabside lowers, of course it’s small pin .250

as you can see its slightly tapered,ball ends up just outside of the receiver. one of my early A2s came with that pin. I got one of the amherst ones and its exactly like the one i have from colt,dont know if its nos or a very good repo. the bearing popped out on mine after 30 odd years of use.
the one i got is from amherst.
