Beautiful rifle. Have the Browning model with the button mag and did not know they made any with full length mag.
They are neat rifles. I hunted coastal black white a bunch with my wife's prior to having it engraved as a button mag. Browning never made a full length mag tube 53. I added full length mags to both our guns so we could use them in SASS. I did keep a spare forearm, cap and button mag though for hunting

Handy little rifles with true rifle velocity ammo.
