The Farnell catalog in the UK now carries 'Multicomp' UHF plugs with a
solderless pressure-sleeve shield clamp (rather like the MA/COM improved
N type). You tighten down with a wrench to make a solid shield contact
that's strong enough to swing on. Only the center pin needs to be
soldered with a small iron.
The connectors have a gold-plated center pin, Teflon insulation, and
nickel-plated brass body. RG58 uses a completely different plug body,
not a reducer.
They are more expensive than standard PL-259s, but a real lifesaver for
outdoor use.
Farnell/Newark in the USA might have them... they're worth seeking out.

You can make a great connection to the shield with a much lower wattage iron
(50W) by drilling the 4 holes one drill size larger, beveling the holes with
another larger drill and adding soldering paste in the hole. I had an
article on this in CQ about 35 years ago. It works great with pollyfoam coax
also--no foam bleed out. I've even wrapped the pollyfoam shield with #40
bare copper wire, quickly tinned it and then inserted into the PL 259. k7gco
