Toni System machines two aluminium base pads for HS Produkt magazines, one for 9x19 and one for .45 ACP, because the magazine bodies differ.
Which pistols
They are listed for the HS-9 and the SF19 in both lengths, along with the Springfield XDM.
What they improve
The enlarged base gives your palm a bigger target to slap, and its texture keeps a gloved hand from slipping. The extra mass helps an empty magazine drop clear.
Protection
When a magazine hits gravel or concrete during a reload, the aluminium takes the impact instead of the feed lips.
With a magwell
Toni System's magwells for the same pistols are made to work with these pads; check both listings if you fit them together.
Model pages include Base pads for HS Produkt SF19 and Base pads for HS Produkt HS-9.
Frequently asked questions
Do they add capacity?
The listings do not state extra rounds.
How do I choose?
By the calibre of your magazine.
